R.saver is a free data recovery program. Recovering deleted files using R.Saver

The article describes the principles and methods of software data recovery for users who do not have special knowledge.

If the value of the information is very high and/or the storage medium is physically damaged, you should consider contacting specialists. In this case, the probability of complete data recovery will be highest.

When recovering data yourself, you should take note of the following information:

• Writing to a partition with recoverable information can reduce the likelihood of data recovery because data may be written over existing data. This also applies to installing data recovery programs and saving recovered files.
• It is advisable to minimize all work on the original drive to increase the chances of recovery. A good practice is to create a sector-by-sector copy of the drive and use various recovery methods on the copy.
• If the storage medium is physically damaged (primarily this applies to hard drives), then any impact can aggravate the situation. You should continue recovery yourself only if the cost of the data itself is lower than the cost of restoring it by specialists.
• Checking the disk for errors using Windows will create additional difficulties for data recovery, up to the complete impossibility of their recovery.

Disk structure

To better understand further actions, we will talk about the logical structure of the disk and file systems. If you are not interested in theory and need to quickly recover data, you can skip this section and go directly to the algorithm of actions.

MBR

Master Boot Record - the master boot record - is located in sector zero of the disk, contains part of the executable code, as well as information about the four partitions and which partition is bootable.

If the MBR is healthy, then after receiving control, the code contained in it reads the partition table and transfers control to the code contained in the first sector of the boot partition (VBR - Volume Boot Record), if it contains the 55AAh signature at the end of the sector.

Otherwise, you may receive an error message such as: “Reboot and select a proper boot device” or “Invalid partition table” or “Missing operating system.” All of the messages listed can occur due to a malfunction in the MBR or VBR, or for other reasons (the wrong boot disk has been selected, etc.).

To restore a damaged MBR or boot partition, there are specialized utilities such as testdisk (Windows) and gpart (Linux), you can also use the “Recovery Console” from the Windows installation disk. Their use will not always give a positive result when recovering data, since in addition to damage to the MBR and VBR, there may be other faults, so these options will not be covered in the article. And although there are enough instructions on the Internet for troubleshooting such problems, it is recommended to first recover important data from the drive, and then try to restore its correct operation.

File systems

Any partition containing a file system consists of the following parts:

1. The bootloader region (VBR), which contains information about the partition structure as well as executable code.
2. An area of ​​data that is divided into equal parts, called clusters, with each cluster having a unique number. The cluster size is set during formatting.
3. An area of ​​file system service data that can store information about folders, files, their names, attributes, as well as information about which cluster chains a particular file occupies.

The locations of the parts, as well as copies of the service data, depend on the type of file system.

Let's take a closer look at the most popular file systems on user computers: FAT and NTFS.

NTFS

The structure of the NTFS file system is shown schematically in the figure.

The partition begins with a boot area, which contains information about the partition as well as executable code. A copy of the bootloader is most often located at the end of the partition.

The next area is the MFT (Master File Table). It is where information about directories, files and their attributes is stored. Typically, a disk area equal to 12.5% ​​of the partition size is reserved for MFT. The size of the reserved area can change (either up or down), and the table itself can be fragmented.

In addition, a certain area of ​​the section contains a copy of the first 4 service records of the table.

The user data area occupies the remaining space of the partition.

When deleting a file Using standard OS tools, only a mark is placed in the file record that the file has been deleted, and the space it occupies is marked as free. If, after deleting a file, no writing was made to the disk, the file remains in place and its recovery is possible.

When formatting a partition a new MFT is created in place of the old one. Initially, the size of the new table is small enough (several hundred MFT records), so some service records from the previous file system can still be restored. The more files were written to the formatted partition, the less likely it is to successfully recover data.

In this case, the data physically remains in its place, and some of the information about it that was stored in the previous version of MFT is also preserved. These files cannot be read using standard OS tools.

Sometimes full formatting is called low-level formatting, which is a mistake. Low-level formatting is a technological operation that is performed during the manufacture of a drive, and it cannot be carried out using software methods.

In fact, only two types of high-level formatting are available from the operating system: full and quick. A quick format simply creates a partition table, while a full format first checks the entire disk for bad sectors. In Windows XP, this check occurs using a read operation (that is, the data remains in place, and therefore, in terms of recovery, this situation is no different from the quick format discussed above), and in Windows 7, sectors are checked by writing, and the data is destroyed irrevocably, and there is no way to restore them.

FAT

The structure of the FAT file system is shown schematically in the figure.

At the beginning of the section there is a VBR, its copy is usually located through 6 sectors. After a certain number of sectors there is the FAT (File Allocation Table) file table itself, followed by its copy.

The file table stores information only about the chains of clusters that occupy files. File names and attributes are stored in directories located in the user area.

The user area in FAT starts from the root directory, all other directories and files are located in it. Directory entries point to the first entry in the file table, which contains information about the file's clusters.

When deleting a file the first character of the file record is changed to a special code, which means that the file has been deleted. Clusters are also marked free and information about the chain of clusters occupied by the file is deleted, which complicates the procedure for restoring fragmented files. The data area remains unchanged, meaning the files can still be recovered.

When formatting a new file table and root directory are formed, the size of the table is indicated at the beginning. The data itself, in general, remains on disk. What follows on the disk after the newly created table remains untouched (that is, information about the location of the files that were on the disk before formatting). As new files are written, directory and file structure data is replaced by new ones, reducing the likelihood of recovering existing information.

Data Recovery Methods

There are both purely software methods of data recovery, as well as software and hardware. The latter require special, expensive equipment, relevant experience and knowledge, while software recovery using automated utilities is available to almost any PC user. It is this method that will be described below.

Recovering Deleted Files

To restore files deleted by standard operating system tools, you need to read service data, bypassing the file system interface. In this case, you can obtain information about the location of files that are marked deleted.

If no subsequent recording to the disk was made, then the required file can be read from this location.

Reconstructing a damaged file system

This method is used when the file system has been damaged or formatted. To reconstruct the file system, it is necessary to scan the entire partition to search for remnants of service data, on the basis of which the file table will be reproduced and, if successful, access to files and folders stored in the partition will be obtained.

Recovery after changing the disk partition structure

Specialized utilities scan the drive for file system structures that exist on the disk. Based on the scan, a list of possible file systems is built with a preliminary assessment of their state. The next step is to check the found systems for the presence of the necessary data.

Recovery by signatures

RAW-recovery - signature-based recovery, used in cases where other methods have not given satisfactory results. In this case, the drives are scanned sector-by-sector for the presence of known signatures (a unique set of characters characteristic of a specific file type).

For the found files, neither the names, nor the logical location, nor the attributes are known. If the files are fragmented, this recovery method will not be effective.

If the signature of the beginning of the file has been found, then the next task is to find the end of the file. Typically, any next known signature is used for this, which may give unsatisfactory results. Modern programs use methods that use residual data about the file system and its features to improve the result. In some cases, such algorithms can help restore even a fragmented file, which is impossible when using standard algorithms. For example, the IntelliRAW algorithm used in the UFS Explorer family of programs works in conjunction with file system reconstruction algorithms and uses this information to determine the end of files. This implementation allows one to achieve better results than using simple signature-based recovery methods.

A rough recovery can give a good result when the files on the drive are located sequentially, without displacement or fragmentation. For example, when recovering files from memory cards of cameras, camcorders, etc.

Data recovery algorithm

We will present the algorithm using the example of a free program that is available for non-commercial use in the former CIS. It is compact, easy to use and does not require installation. Uses commercial software algorithms and produces results at the level of professional utilities. NTFS, FAT and exFAT file systems are supported.

You can download it from the support page on the official website: .

The archive with the program must be unpacked onto a partition different from the one from which the recovery will be carried out. If the system has only one partition, the best solution would be to connect the disk with the recoverable data to another computer. If this is not possible, you can unpack the program to an external drive (if it is large enough to save the recovered data).

Section selection

After unpacking the program, you need to run it. On the left side of the main window you can see the drives connected to the system and the partitions on them. If the desired section was automatically found and displayed in the list, select it and move on to the next item.

If the required partition is not in the list (for example, the drive was formatted or partition sizes were changed), you can search for the lost partition or set it yourself (only if you know the exact parameters of the partition). You can select these functions in the drive’s context menu or on the toolbar.

Let's take a closer look at the lost partition search function:

After launching it, a new window will open in which you need to click on the “Find Now” button, which will start a search for known file systems on the disk. As they are found, the list will be supplemented with information about the sections found. The most likely options will have a blue icon, which means the partition is in good condition. If the icon is yellow or red, then the found partition is either very damaged or found incorrectly (some types of files can give this effect).

From the list of partitions, you need to tick those that most closely match the parameters of the partition you are looking for: beginning (in sectors), size (in sectors and megabytes), label, file system type.

If the value in the "size" column is less than the value in the "start" column, then the section is most likely not valid. Typically these "bad" partitions are disk images stored on the drive.

To continue, click the “Use Selected” button.

Scanning

If a partition with the NTFS file system was selected, you will be offered a choice: run a full or quick scan.

The scope of application of quick scanning is to search for files deleted using standard operating system tools. This scan only reads service records in the file table and analyzes them.

Full scan is used in most cases. This involves searching for remaining service records in the file table, virtual reconstruction of the file system, and sector-by-sector scanning using IntelliRAW technology. Gives excellent results, but takes longer.

For FAT16/FAT32 and exFAT file systems, only full scan mode is available. This is due to the fact that due to the nature of these file systems, in many cases a quick scan is not enough to effectively recover data.

Saving results

After the scan is completed, the program will show the result of the reconstruction in the form of a tree of files and folders that were found.

Blue icons display elements that are visible by standard operating system tools, red icons indicate those that have been deleted or lost and are inaccessible by standard operating system tools.

In addition, service folders will be available:

• contains files and folders whose location could not be linked to the root directory
• contains files sorted by type found using signature recovery (with IntelliRAW technology)

To save the recovered data, either select “Copy to...” in the element’s context menu, or click the “Mass selection” button on the toolbar, then select all the necessary elements and click the “Save selected” button.

Let us remind you that it is necessary to save the recovered data only on a partition different from the one from which the recovery is being carried out - otherwise the data may be damaged.

Hello friends, today we will talk about user data, which is an integral part of any computer. We store many files and folders of files on these devices. Of course, there are also important documents that should not be lost. The bottom line is that all this important data can disappear at any time, since 100% protection does not exist, the drive can fail, a virus program can work, anything can happen.

But not on purpose, of course, but by pure chance, then in this instruction I will try to describe a way to return this data. Go.

Data recovery using R.Saver

We already have it on our website a review article on the Recuva program, which is also capable of recovering data, but it is quite simple, so I found a more powerful, in my opinion, tool with more functionality. Today I will talk about a free, simple, but most importantly effective program called.

As the developers of the utility themselves say, the utility is capable of recovering deleted files on various drives with different file systems, be it . The program can also reconstruct damaged file systems and restore files after formatting the drive. It can also find deleted partitions.

R.Saver works on Windows and Linux OS, it can work with other systems, and also view files on many file systems, details can be found on this site. You can download the program there.

The most interesting thing is that the program does not need to be installed. Convenient right? You just need to unpack the archive to some place, but do not unpack it to the disk from which you will perform the recovery.

As soon as you launch the program, all disks and partitions will be available to your view. Let's get started already.

High-quality computer repair, the main office is located in St. Petersburg.

For example, I will create a folder on one of the disks and copy a couple of files there, for example, pictures, music, files of different types and sizes in general.

Now we will delete these files.

We go to the R.Saver utility, select our disk from where we deleted the files and right-click on it, and select "Search for lost files".

A window will pop up asking you to perform a full scan of the file system. Since we did not format the disk, but deleted the files ourselves, we will choose the option "No". Of course, otherwise, you need to click “Yes”.

There will be a process that won’t drag on for very long, although it depends on who it is. At the end of the process, we should see our data folder, which is highlighted in a different color compared to other files.

We can open it and see what the program was able to find.

Now, if you are convinced that all the files have been found, you can click the button "Save selection", do not forget to select the folder or files before doing this.

A little time will pass and the files will be at your disposal, you can enjoy the recovered data.

This program is capable of recovering an entire partition that has been formatted, or a damaged partition. To do this, select the appropriate item "Recover after formatting".

I would also like to note this point: if the file systems of partitions and disks are different, then in the main program window they will be marked in different colors, for example, like this:

• Red color – damaged file system structure;
• Blue color – the file system is in normal condition;
• Yellow color – the file system is POSSIBLY damaged or belongs to a RAID array. I wrote about RADI arrays;
• Gray color means that the program did not find supported file systems.

Now you will know what and how, you shouldn’t be scared, so you can find out what condition the drive is in, so to speak, mini-diagnostics.

That's all, I've given you a little instructions on how to use the program, but you can find more information on the developer's website. In the folder with the program that you unpacked there are instructions that you can read.

The free program R.Saver is a utility for recovering user data from various drives. Whether it’s a flash drive or a hard drive, it’s not so important, the main thing is that the drive is in good working order. R.Saver recovers data from damaged file systems such as NTFS, FAT and exFAT. It also restores files after formatting.

Hello friends. Max in touch! Today we will talk about the R.Saver program. The program was created on the basis of a fully functional algorithm of the professional version of the program. The program is easy to use with an intuitive interface. R.Saver is available for download from the developer’s website at this link.

According to the developers, the R.Saver program allows you to perform the following actions:

• Recover deleted files;
• Reconstructs a damaged file system;
• Data recovery after formatting;
• File recovery based on signatures;

The R.Saver program also makes it possible to copy and view data from such file systems as:

Microsoft Windows: exFAT, FAT12, FAT16, FAT32, NTFS, NTFS5;

Apple Mac OS: HFS, HFS+/HFSX;

Linux: Ext2, Ext3, Ext4, ReiserFS, JFS and XFS;

Unix, BSD, Sun Solaris: UFS and UFS2 (FFS), including big endian UFS, which is used on Sparc/Power servers;

Novell Netware: NWFS;

CD/DVD: ISO9660, UDF;

R.Saver does not require installation; just unpack the archive, for example with a program, but not to the partition from which you will be restoring. Then run the program, tap on the file with the .exe extension. The program interface is something like this.

The main menu of the program, as well as a list of all disks, partitions, their size and file system is located on the left. On the right is the information panel, as well as the information panel toolbar.

Recovering deleted data using the R.Saver program:

Let's now create a folder with files on the flash drive and put various files with different extensions there. Let’s call the folder “Folder with files.”

Then, delete this folder with all its contents.

Then, to restore deleted files, run the R.Saver program. Now select the flash drive, right-click and select “Search for lost data.”

In the next program window, you need to answer the question “Do you want to perform a full (sector-by-sector) scan of the file system?” and select one of the items.

• If you answer “Yes”, a full scan will be performed ( recommended after formatting);
• If you answer “No”, a quick scan will be performed ( to quickly search for deleted files);

In our case, you need to select “No”, since I just deleted the folder manually. If the flash drive has been formatted, then you must select “Yes” for a more thorough scan and search for deleted files.

After scanning is completed, we will see our folder highlighted in brown in the program window.

Then you need to select the folder with the found files, and then click on the “Save Selected” button.

And indicate the place where to save all this found stuff. Then click the “Select” button".

Here is a program that I think will be useful to many PC users. Using the free program R.Saver, you can recover entire partitions on hard drives, as well as from damaged partitions, or from those partitions that have been identified as unknown. After formatting, there is a corresponding item “Restore after formatting”. That's all, bye to everyone and see you soon.

Sincerely,

A USB flash drive is not the most suitable device for permanently storing files, but anything can happen in life. And situations when valuable data located only on it were accidentally erased happen regularly. However, in about half of the cases, grief can be helped by recovering deleted files from a flash drive. Under what circumstances is this possible and how to do it, read on.

I won’t get my hopes up in vain: the chances of successful data recovery from USB flash drives are lower than from stationary drives - hard drives of PCs and laptops and permanent memory of mobile devices. The reason is that flash drives are usually used to transfer files from one device to another. And accidentally deleted data most often ends up being simply overwritten, sometimes even more than once. And overwriting, unfortunately, destroys the information irrevocably.

Full or partial file recovery on your own is possible in the following cases:

• The user deleted them manually.
• The drive was formatted using the operating system.
• The files became inaccessible after a virus attack.
• The files disappeared after splitting the flash drive into partitions.
• A logical failure of the file system has occurred: it has become defined as RAW - unknown, or Windows and programs consider the entire space of the device to be unallocated.

The chances of recovery are extremely low or zero if:

• The flash drive is physically faulty - it is not detected by the computer at all or is recognized as an unknown device, access to its memory is either completely absent, or the size of the latter is several KB instead of tens of GB. The exception is relatively simple breakdowns that do not affect the controller and device memory.
• The files were deleted using a shredder program.
• The flash drive was low-level formatted (essentially repartitioned and rewritten) or reflashed (the controller microcode was rewritten).
• The files are encrypted, but there is no decryption key. It may be the result of an attack by a ransomware virus or user actions (encrypted, but lost the key). In the first case, it is sometimes possible to recover files if you have a suitable decryptor.

In case of physical and complex logical faults, data recovery from flash drives is sometimes possible, but often costs the owner very much - up to several tens of thousands of rubles (not even the result, but the attempt at recovery, can cost that much). Therefore, in such situations, many people prefer to say goodbye to files forever.

How to increase your likelihood of success

Even if your case falls into the simple category, in order to increase the chances of a successful recovery, adhere to the following rules:

• The fewer operations were performed on the drive's file system, the better the result. Therefore, start recovery immediately as soon as you notice missing files.
• Save the recovered data only to another physical medium (computer hard drive, second flash drive, etc.).
• Try to restore everything in one session. Don't interrupt unless absolutely necessary.
• If one recovery program does not help, use others. Sometimes simple free utilities are more effective than expensive paid ones. It is impossible to know in advance what will help in your case, so try everything that is available.
• If the recovery program is capable of creating and saving images of drive file systems, be sure to use this feature. In case of unexpected failure of the flash drive or accidental overwriting before the end of reading, you can restore the data from the image.

7 best programs for data recovery from flash drives

You may already be familiar with some of the storage device data recovery programs. Our site talked about them in an article about. Today our collection will be replenished with seven more applications of the same purpose. Maybe one of them will be life-saving for you.

R.saver

Wise Data Recovery

Wise Data Recovery is another worthy tool for recovering information from desktop and portable drives. Available only in Windows version. Like its predecessors, it works without installation on a hard drive. It has a high scanning speed and displays the possibility of restoring each found object.

If next to the file there is:

• Red circle—data has been completely overwritten and cannot be restored.
• Yellow circle—overwriting is partial, success is not guaranteed.
• Green circle—the file has not been overwritten and is recoverable.

When you click on “green” files, if it is a picture or document, the program shows their thumbnails (if saved). It also has a function to search for certain types of data using keywords: pictures (imagies), audio (audios), videos (videos), documents (documents), archives (compressed files) and mail (emails).

Wise Data Recovery is a completely free application and, by the way, supports the Russian language.

How to use Wise Data Recovery:

• Unpack the archive with the program to any folder and run the executable file WiseDataRecovery.exe.
• Select the desired media from the list and click “Scan”.
• Select the files you want to recover from the list. Click the "Recover" button.
• Specify the location to save the files on your hard drive.

Disk Drill

The Disk Drill utility, well known to many Mac OS X users, appeared in the Windows version some time ago. More precisely, in two: free - free, and paid - pro. The free one allows you to recover up to 1 GB of information, the paid one - without restrictions.

Unlike the three previous applications, Disk Drill requires mandatory installation on the computer (for which it receives a minus, since this simple operation can lead to overwriting the data that the user was just about to restore). But it has a number of benefits that others do not have.

With constant use, Disk Drill keeps track of deleted files and also creates backup copies of them, which increases the chances of their recovery even after a while. In addition, it supports any type of storage device and almost all file systems (it knows more than 300 unique file signatures).

Disk Drill does not have a Russian localization, but it is quite easy to use.

How to recover deleted files using Disk Drill:

• Install the application on your PC and run it with administrator rights.
• Select a USB flash drive with deleted data from the list of media.
• Open the drop-down list next to the Recover button, which is located opposite the flash drive, and click the desired scan type: “Run all recovery methods” (use all search and recovery methods), “Quick scan” (quick scan), “Deep scan” (deep scan) ) or “Load last scanning session” (load the result of the last scan). Click the "Recover" button (or "Continue" if you have already started working with the media).
• In the next window that opens after scanning, select the desired files from the list, specify the location to save them and click “Recover” again.

RS File Recovery

RS File Recovery is a paid Russian-language application. In addition to the main thing - restoring information from physical drives, it is able to save and subsequently work with their images. After creating the image, the physical device with the data can be disconnected, since the program has already “remembered” all its contents. In addition, the application has a built-in HEX editor for manual byte-by-byte correction of files, as well as an FTP client for uploading the recovered file to network resources.

After analyzing the storage device, RS File Recovery displays information about the data on it - when it was created, when it was changed, and whether it can be restored. This information appears in the bottom pane of the window.

Unfortunately, in the free demo version of the utility, the recovery function does not work, only viewing is available. The cost of a license starts from 999 rubles.

Like Disk Drill, RS File Recovery requires installation on your computer.

How to use RS File Recovery:

• Launch the application. Select a flash drive from the list of media by simply clicking on it. All its contents, including deleted files, will be displayed in the middle part of the window.
• Click on the item you want to restore. Information about it, including the forecast, will be shown in the panel below.
• Drag the required files to the recovery list on the right side of the window and click the “Recover” button.
• Select the saving method: to hard drive, to CD/DVD, to the Internet via FTP, or to convert to a virtual ISO image.

• Specify the destination folder on your hard drive. Follow the assistant's instructions when selecting other saving methods.

Ontrack EasyRecovery

Ontrack EasyRecovery is one of the most functional and effective data recovery programs, the main competitor of industry leader R-Studio. It successfully extracts data even from heavily damaged media, supports all types of file systems and more than 250 file formats, creates virtual images of physical storage devices, can boot from DVDs and USB flash drives, and also has a lot of other useful features.

EasyRecovery is available in several paid editions with different sets of functions. The most inexpensive is home-based, which will cost the user $79 per year. Professional, enterprise and specialized (for servers) cost from $299 to $3000 for an annual license.

Despite the enormous possibilities, even a novice user can use this program, since each stage of the work is accompanied by a built-in assistant. It is also impossible to make a mistake because it is completely translated into Russian.

How to use Ontrack EasyRecovery:

• Launch the application (it is available in installation, portable and, as already mentioned, boot versions). Specify the type of media on which the deleted data is located.
• Select the volume to scan (if it is a flash drive, then, as a rule, there is only one volume on it).
• Select a recovery scenario. Restoring objects after deletion and formatting are different scenarios. First, try using the first one - it works faster, and if that doesn’t help, try the second one.
• If the data was affected by a logical failure, identify one or more types of file systems that may be on the media.

• Check again that the conditions are correct and confirm your selection. After this, the program will begin scanning the flash drive.
• After scanning is complete, select the desired objects in the list (to select several, press and hold the Ctrl key). Click the “Save” button in the top panel of the main window and specify the destination folder on your hard drive.

To create an image of a storage device and work with it in the future, after starting the program, select the device in the list of media, open the “File” menu and click “Create image file”.

Active UNDELETE

Active UNDELETE is another paid utility that successfully copes with the recovery of individual deleted objects and entire disk partitions. Supports all types of media, all file systems and over 200 different file formats. In addition to the main tasks, it allows you to solve related problems - correct errors in partition tables and boot records, create, format and delete disk volumes, etc. Like the majority of paid analogues, Active UNDELETE supports the creation of virtual images of drives.

The demo version of the program, available for free download, has a full range of functions, but does not allow you to recover files larger than 1 Mb.

The Active UNDELETE interface is exclusively in English, but the utility is easy to use, since each action is accompanied by a wizard.

Unfortunately, it does not have a portable version. Installation only.

How to work with Active UNDELETE:

• Launch the program. Click “Recover deleted files” in the first window that opens. This will launch the recovery wizard.
• The first window of the wizard is a brief summary of how the program works in English. To proceed to the next step, click “Next”.
• Next, select one or more devices on which the desired files are located. Click "Next" and in the next window - "Scan".
• After scanning, mark the items you want to recover and proceed to the next step.
• Set the saving options - folder, file names, renaming in case of matches, etc. You can leave everything as default.

• The last step is the actual recovery. To launch it, click the “Recover files and folders” button.

If you want to create a virtual image of a flash drive, open the “Disk image management” section in the main window and run the “Create disk image” wizard.

An easy-to-use program for recovering files from different versions of the FAT and NTFS file systems.

Created based on professional versions of UFS Explorer products. Only non-commercial use is allowed in the territory of the former USSR.

You can start scanning by pressing one button, the settings will be done automatically. In this case, the program performs:
* Reconstruction of damaged file systems.
* Data recovery after formatting.
* Recover deleted files.
* File recovery based on signatures.

The following file systems can be accessed in read mode:

* Microsoft Windows: FAT and NTFS, including FAT12, FAT16, FAT32, NTFS, NTFS5.
* Apple Mac OS: HFS, HFS+/HFSX.
* Linux: Ext2, Ext3, Ext4, ReiserFS, JFS and XFS.
* Unix, BSD, Sun Solaris: UFS and UFS2 (FFS), including big endian UFS, which is used on Sparc/Power servers.
* Novell Netware: NWFS.
* CD/DVD: ISO9660, UDF.

System requirements

* Operating system: Microsoft Windows 2000/ 2003/XP/ Vista/Windows 7.
* Pentium or compatible processor.
* At least 256 MB RAM.
* At least 10 MB of free hard disk space for installation.
* Availability of a “default” Internet browser.

Installation

Just download, unpack, and run the executable file. As such, no installation is required. Attention! Save, unzip and use on a partition different from the one from which you want to restore information.

Features of use

The program itself chooses the scanning method depending on which file system structures were found first. Therefore, if you have formatted a partition with important data, changing the file system type from FAT to NTFS or vice versa, we recommend using one of the versions of UFS Explorer to recover data.

Interface

Partition selection window

The window appears immediately after starting the program.

The main menu is a panel with buttons that can be used to open a drive image or virtual disk, update the list of devices and partitions, and also view the manual and brief information about the program.

The partition list displays on the left side of the window a list of storage media and the logical partitions detected on them.

Devices are indicated by icons in the form of hard drives, partitions are indicated by round icons of different colors:

* Blue color means that a preliminary check of the file system contained on the partition showed its satisfactory condition.
*Orange indicates any damage.
* The program marks in gray the partitions on which there are no file systems supported by R.saver.

Detailed information about the selected list item can be seen in the information panel on the right side of the window.

The information panel displays detailed information about the device or logical partition selected in the list on the left.

The information panel toolbar contains icons for launching functions applicable to the object selected in the list of sections. Depending on its type, the following sets of buttons are possible:

A. This computer. The same functions are called as when pressing similar buttons on the top panel.
* "Open"
* "Update"

B. Storage.
* “Define partition” If you know the parameters of lost partitions, you can set them manually using this function.
* “Find Partition” This button starts a scan that allows you to find lost partitions, as well as determine the file system type if the program failed to do so at startup. See section search.

C.Section.
* “View” Opens a file manager window.
* “Scan” Starts the data recovery process on the selected partition. See data recovery.
* “Test” Available only for partitions on which file systems are found. The function allows you to check the correctness of the metadata of files and folders.

File manager window

Used to navigate through the contents of sections, launch and analyze scan results, as well as save found files and folders.

The left panel displays the contents of the current section in the form of a folder tree. After scanning, you can see its results here in the form of virtual root folders that appear.

The right pane displays the contents of the selected folder.

The file manager toolbar, depending on whether the current partition has already been scanned or not, may contain the following functions:

A. If the scan has not yet been performed.

* “Scan” Starts scanning the current partition. See data recovery.
* “Load scan result” Loads the saved result of a previously performed scan.
* “Save Selection” Copies the selected files and folders to the location specified using the pop-up window.

B. If a scan has already been performed.
* “Sections” Clicking this button will return you to the section selection window.
* “Scan” Restarts the scanning process.
* “Save scan” Saves scan results.
* “Save Selection” Saves files and folders to a location specified using a pop-up window.

The address bar shows your current location and makes navigation easy. In order to climb up the directory tree, just click on the name of the corresponding folder. If you click on the empty space after the last element of a line, it will be converted into a text view that can be edited.

The search line allows you to search for a file in the current folder and its subfolders, just enter its name in the line and press the “Enter” key. The symbol “*” can be used. For example, to search for files with the jpg extension, you should enter “*.jpg” in the line.

The advanced search form can be called via “Ctrl+F”.

I. If the required sections are not in the list, look for them.
II. Scan the selected logical partition.
III. View the results and save the necessary files.

l. Search for sections

Use this function when the partition from which you want to recover data was not automatically found and displayed in the list under the device on which it is located. If the required partition is identified correctly, proceed directly to scanning.

Searching for partitions with FAT and NTFS is supported. Select a drive in the list and click the “Find partition” button on the toolbar of the information panel. A window will appear in front of you from which you can start the search process or load previously saved results.

After the scan is completed, a list of expected partitions will be displayed.

Then check off those items in the list that are in the best condition (see the color of the icons) and are similar in parameters to the sections containing the information you are looking for. Click the "Use Selection" button.

If a partition found and added to the list is indicated by a blue icon, then it may be possible to recover data from it without running a scan. This happens in cases where damage affected only the partition table. To test this assumption, use a test launched from the dashboard toolbar. If it does not detect errors, click the “View” button and proceed to selecting and saving files.

If the icon of the found partition is not blue, or the scan found errors, or if the required data is not among the contents of the partition, start scanning.

ll. Scanning

You can launch it by clicking the “Scan” button in the file manager toolbar or the information panel of the partition selection window. The progress bar that appears will reflect the progress of the process.

After the scan is completed, virtual folders with its results will appear at the root of the directory tree:
“Reconstruction result” - contains a virtual file system built on the basis of the collected information.
“Deleted files” - contains detected deleted files.
“Damaged files” - supposedly damaged files go here.
“Found by type” - the result of searching for files by signature. Practice shows that in the case of NTFS this is rarely advisable. At the same time, the process itself is long and resource-intensive. Therefore, R.saver uses this algorithm only when recovering data from FAT.

It is also recommended to save the scan result before performing further actions. For this purpose, use a partition different from the one on which the data was lost.

lll. Studying the result and saving the found files

To simplify this process, the program provides a preview function. It makes it possible to open individual files directly from the reconstruction results by double-clicking on their names.

Attention! When using preview, the program will ask you for the path to the folder that will be used to store temporary files. It must be on a partition different from the one from which the data is being restored.

After you decide which files and folders you need, select them in the list and click the “Save Selected” button on the toolbar. To simultaneously select multiple files or folders in the right pane, hold down “Ctrl” on your computer keyboard. The location where the data will be restored must be on a partition different from the one you are working with.
