How to split a file into parts? Splitting files How to split a file into several archives
I think many people have encountered the fact that a file or folder exceeds the required size limit (for example, when sending an attachment by mail, uploading it to an FTP server, or recording it on any media), one solution is to archive the data, since it will help reduce the size folder or file. But if this is not enough and even the archive cannot be compressed to the required limit, in this case the file or folder can be divided into several archives of the required size.
This is what this article will be devoted to - how to split/split a file or folder into several archives using the Winrar or 7-Zip archiver.
Split/split a file or folder into multiple archives using WinRar.
We have a site folder that needs to be archived into several archives. To do this, right-click on it and select "Add to archive".
In the window that opens Archive name and parameters, in the " Are common", we see a field at the bottom left "Split into volumes of size (in bytes)", you can use the already specified parameters, for example, if you want to save to a floppy disk (although I think this is no longer relevant) or CD. If you are not satisfied with the prescribed sizes, you can specify your value, just remember that the value is indicated in bytes!!!
Let me remind you:
1 Kilobyte (1Kb) = 1024 bytes,
1 Megabyte 1 (MB) = 1048576 bytes,
10 Megabytes (10 MB) = 10485760 bytes.
Accordingly, if I want to make archives not exceeding 10 MB. You must register 10485760.
Click "OK". As a result, I ended up with several archives whose size does not exceed the specified value of 10 MB.
Split/split a file or folder into multiple archives using 7-Zip.
Right-click on the file or folder you want to archive and select "7-Zip-Add to archive".
In the window Add to archive there is a box at the bottom left "Split into volumes of size (in bytes)", in this field we select or enter the required size, in this case I want to split it into archives of 10 MB and there is a specified size, so I simply select it (you can also enter 10485760 - the result will be the same)
As a result, several archives appeared that did not exceed 10 MB.
In order to correctly open the created archives, you need to place them all in one folder and open the first archive.
It is not uncommon for a situation to arise when you need to send a file by mail, but its size exceeds the permissible threshold. As a rule, in such situations, other methods of sending the file are used. For example, a file is uploaded to cloud storage and a link is sent with which this file can be downloaded. However, there is another way. A large file can be divided into parts and sent in several emails. In this article we will tell you how this can be done.
If you don’t know how to split a file into parts, then the first thing you need to do is download and install the archiver. In this article we will use the 7zip() archiver, but you can use WinRAR or any other that is convenient for you.
After downloading and installing the 7zip archiver, call the context menu (right-click) for the file that you want to split into parts. In the menu that opens, select “7-zip – Add to archive”.
After this, a window with archive creation settings will open in front of you.
At the bottom of this window there is a "Split into volumes" function. Using this function we can divide the file into parts of the size we need.
In order to divide the file into parts, you need to enter the size you want to receive. The size is entered in megabytes. To do this, enter the number of megabytes with the English letter “M”. For example, 5M, 10M, 15M, etc. You can leave the remaining archiving settings as default or change them as you wish. This will not affect the process of splitting the file into parts. The only note is that the archive format is best set to “zip”. This is the most popular format; using this format, you can be sure that there will be no problems opening it on another computer.
After you have entered the file size you want to receive, you can click on the “OK” button and start the archiving process.
For example, we split the file into 15 MB parts. After this, archive files appeared in the folder with the source file. The size of each file will not exceed the size you specified in the archiving settings. You can verify this by looking at the file size.
At this point, the process of dividing the file into parts can be considered complete. You can send the created archive by email, attaching one file to each email.
In order to unpack such an archive and get the original file again, you need to place all parts of the archive in one folder and use the “Unpack” function.
Computer programs are becoming more complex, movies are getting better quality, and games are getting better graphics. All this leads to the fact that file sizes increase, and if a film in a small resolution of 360p or 720p can be transferred from computer to computer without problems, then when the resolution reached 4K, this became more difficult. In such a situation, it is necessary to split the file into parts and then merge it back together. There are several ways to do this, but first of all, we suggest dealing with situations in which you may need to split the file into several parts.
Why split the file into parts?
With the advent of external hard drives, many people no longer need to split large files into parts. Large files can be easily downloaded to a spacious external drive, and then transferred from it to another computer. But there are situations in which it is necessary to split the file into several parts, and here are just a few of them:
We have listed only three of the most common situations in which you may need to split a large file into several parts. In highly specialized areas, there may be other reasons, for example, you may need to split the file to provide additional security and the inability to access it without combining all parts into one. We suggest considering two of the simplest ways to split a large file into several parts.
The most common and easiest way to split a file into several parts is to use the WinRar archiver program. This method is the simplest, since the WinRar program is installed on most computers, and it is not difficult to assemble a divided file into parts, as well as to “cut” it. Please note that the following instructions require WinRar to be installed.
To split a file into parts in WinRar you need to:
How to combine files divided into parts in WinRar:
As you can see, the process of splitting a file into parts using WinRar is quite simple. Its advantages include archiving of selected files, that is, after breaking into parts they weigh less than the original object. This allows you to split the file into fewer parts.
How to split a file into parts using Total Commander?
No less famous program than WinRar among experienced computer users is Total Commander. The program is used for various purposes, including working with files and folders on a computer. It allows you to easily split a file into parts by clicking a few buttons.
To split a file into parts in Total Commander:
How to merge files split into parts in Total Commander:
Unlike WinRar, Total Commander does not archive files, which means that parts of a file will take up approximately the same amount of space as a separate object. However, Total Commander has one serious advantage - it is much faster than WinRar at dividing files into parts and putting them together, which is useful when working with large amounts of information.
Question from a user
Hello.
Tell me, I have one video of 20 GB (video recording of one game). I want to transfer it to another computer, but the file does not fit on my flash drive (it is 16 GB).
Now there is an option - either buy a new large flash drive (or portable disk), or find a way to somehow transfer the file in parts (for example, split the file into 2 parts). I tried to re-encode the video - but you have to wait a whole day, and it’s not a fact that it will be re-converted and become smaller...
Arthur, Petrozavodsk
Good day!
In general, a similar problem was encountered quite often earlier, when the Internet was not so developed and there were no capacious storage devices (now one external hard drive can solve this problem ☺).
In this article I will give several ways in which you can quickly split any file into several parts (the size you need), and then, when you transfer it to another medium, assemble it (so that everything opens and is readable).
Method No. 1: creating a multi-volume archive
One of the easiest and fastest ways to split absolutely ANY file(s) (or even folder) is to place it in a multi-volume archive. Moreover, the volume size can be set manually, exactly the one you need.
For those who are afraid that the archive creation time will be too long, I will say that the archive can be created WITHOUT COMPRESSION! Those. The archive will only be needed to pack information and split it into volumes (by the way, an uncompressed archive is packed quite quickly).
The best free archivers -
We find the folder or file that needs to be divided: right-click on it and select from the Explorer context menu "7-Zip > Add to archive" (see screenshot below).
In the archive creation settings you need:
- compression level: recommended “No compression” (this way you will spend much less time. Moreover, the video file will not be compressed this way);
- Split volumes by size: Enter the maximum file size in megabytes here. Let's say, for a 16 GB flash drive, it will be about 14500 MB (i.e. 14500M), example below.
After creating the archive, you will see that it consists of many parts of the same size. Now, to extract it, you need to extract the very first part of the archive (001) - see the screenshot below. In general, 7-Zip is a fairly “smart” program and will highlight the file you need with its icon ☺.
Method number 2: breakdown in Total Commander
Another very good and reliable way to split a file is to use a special function in the Total Commander program.
Total Commander
A very functional and convenient file manager (in my opinion, much more convenient than the classic Explorer). Allows you to browse directories without any problems, containing thousands of files. It also allows you to easily and quickly work with all popular archives: ZIP, 7ZIP, ARJ, LZH, RAR, UC2, TAR, GZ, CAB, ACE, etc.
There are unique features: group renaming of files (with custom filters and masks), file splitting, working with FTP, etc.
And so, first of all, we launch Total Commander and find our file. In my case, this is an archive with a photo ("photo.7z") - the size of this file is about 1 GB. Task: break it into parts, each of which is no more than 250 MB.
Let's split one large file into 5 parts
First select this file and then click on the menu "Files/Split file..." . See screenshot below.
As I said above, I indicated 250 MB (by the way, the program has all the most popular sizes: for Floppy 3.5 floppy disks, CD/DVD disks, etc.), and indicated the same folder in which the original file is located.
After which, the file was divided into 5 parts (plus the sixth part - the checksum of the file (necessary to check the integrity of the archive, I also recommend saving and not deleting!)).
Actually, now you can transfer all these separated files in any order to another PC, and then also select Total Commander in the menu "Files/Collect file..." . In general, everything is quite simple and fast...
Method number 3: cut the video into parts (without conversion)
If you are dealing with video, then in this case it is not at all necessary to pack it into an archive or resort to the help of Total Commander... You can use some video editor and split the video into certain parts (however, this is not very suitable in this case , if you do not want to cut the video completely, because gluing the video together can be a longer procedure...).
How to do this simply and without “nerves” ☺?
You will need one video editor - VideoMONTAGE.
VideoMONTATION
One of the simplest and most intuitive video editors. The developers specifically made it very simple with a step-by-step wizard so that any user (even a complete beginner) could easily figure out how to edit and create their own video (perhaps the very first!).
The editor has all the most necessary functions for video processing. So, this option is one of the best for solving simple problems and for learning how to process video.
After installing the editor, open the function in it "Video cutting"(this opportunity appears in the first window that appears immediately after starting the program).
Then, when saving the video, be SURE to indicate that you want to save the video in original quality(see screenshot below). This way, the video will be saved without conversion and very quickly. In fact, we simply divided the video into 2-3-4 (or more) parts without editing it!
Well, that's all for me, good luck to everyone!

When archiving files using WinRAR, you can change several options for creating an archive, including splitting it into parts. Let's show it with an example.
Select any files on your computer, right-click on them and click on “ Add to archive…", as shown in the screenshot below.
A window with archiving parameters settings should open in front of you. In its lower left area, find the inscription “ Divide into volumes of size».
Here you can choose what size parts your archive will be divided into. You can enter your number and select a unit of measurement (byte, kilobyte, megabyte or gigabyte), or select one of the most popular values from the drop-down window - 5 MB, 100 MB, 700 MB, etc.
For example, we will choose 5 MB. To start archiving with division, click “ OK».
In the folder next to the original files, if you did not change the folder to save this archive in the archiving options, parts of your split archive will appear.
All volumes will be of the selected size except the last one - there will be so much left. For example, if the whole archive “weighs” 17 MB, then it can be divided into 4 parts, choosing the size of each 5 MB. In this case, the latter will be 2 MB in size (17-5-5-5=2).
