The RAR file is a compressed archive. The archiver converts multiple folders and files into one smaller file. To view and use the contents of the archive file, you need special utilities (programs) for compressing files that are compatible with this format.
InstructionsThese utilities can unpack multiple files and then combine them into one archive file. Many such utilities can decompress a file, but few can create an archive. If you need to merge multiple files back into RAR format, use WinRAR program. It is also possible to combine multiple files into one ZIP, TAR or 7Z archive file using the 7-Zip program.Download WinRAR software from RarLab website and install it. WinRAR is a commercial program, but the website provides a free trial.Open WinRAR and select one of the archive files you want to combine. Click the Extract To button.Click the New Folder button. Name the folder and click OK to extract the files.Repeat these steps to extract other archived files. Specify the folder created in the previous step to extract each of the files.Click the Add button and select the files in the created folder. Click OK.Select the archive location from the dropdown menu. Press the RAR radio button and select OK to create the merged file. Alternatively, you can use the 7-Zip program by going to the next step.Download the 7-Zip software from the 7-Zip website and install it on your computer. 7-Zip is free program, there are versions for Windows, OSX, Linux and other operating systems.Place each of the files you want to merge into one directory. Depending on the number of items in each archive, placing them in a new folder without any other files will help simplify the task.Select files in RAR format. Right click on the file, select the 7-Zip Extract Here option. Wait for the extraction to complete.Hold down the Ctl (or Command on OSX) key and select all the extracted files. Right click on the file, select the 7-Zip Add to option, depending on the type of archive file you want to create. Wait for the compression to complete. The new merged file will appear in the directory.
Using the program WinRAR ... Now let's look at two more features of this program - archiving a file in parts, and creating a self-extracting archive.
Archiving a file in parts
If the file is large and it is impossible to transfer it due to the limitations of the size of mail or file hosting, then you can split it into parts, more precisely, into several archives, and these archives are already transferred.
In the WinRAR program, you can archive in parts. Let's get down to it now.
To archive files, you need an installed WinRAR archiver. If you don't have it, then you can download the archiver using the link at the beginning of the article.
In the window My computer, or in the program Total Commander, right-click on the file you want to archive in parts, and in the context menu select the item WinRAR - Add to archive... If you have an English version of the archiver, then you need to choose Add to archive .
A window appears Archive name and parametersin which you open the tab General if not already open by default. In the English version of the archiver, this tab is called General .
At the bottom, find a window under the item. In the English version, the inscription will be Split to volumes, bytes.
Enter the size of the parts into which your file will be split into this window.
For example, if you have a 6GB file, and you need to split it into archives of 600 MB each, that is, into 10 archives, then enter the number 629145600 in the window, since 600 MB is equal to exactly this number of bytes: 1MB is equal to 1024 KB, and 1 KB is 1024 bytes.
Now press the button OK ... That's it, the file is zipped and will be placed in several archives. The names of these archives will be the same as the name of the source file, with endings separated by a period: .part1, .part2, .part3 etc.
You can safely transfer these archives, or keep them.
Combining them into one file is also very easy. Place all these archives in one folder, and unzip any of them. You don't need to unzip them all, just one is enough. All the parts will then be put together, and you will have a whole file.
You've probably seen any archives, by double-clicking on which, you could automatically unzip them? No need to right-click and look for unzip items. You don't even need to have the program itself - an archiver for unpacking. Everything is inside such an archive.
Self-extracting archive has the extension exe ... To extract such an archive, you double-click on it with the left mouse button, and in the window that appears, select the location where this archive will be unpacked.
If you leave the destination folder by default, the archive will be unpacked to the same folder where it is located, which is very convenient.
Now let's figure out how to create such an archive. Everything is very simple. In folder My computer, or in the program Total Commander , right-click on the file or folder that you want to archive, and then select the item WinRAR - Add to archive.
Naturally, you must have WinRAR installed. Next, put a tick in front of the item Create SFX archive, and click OK .
The abbreviation SFX stands for self-extracting , and is translated from English as self-extracting.
Upon completion of the archiving, you receive this archive in the same folder where the source file or folder is located.
Self-extracting archive in parts
You can also archive the file in parts so that the first archive will be self-extracting. It is easy to do this by combining the method of archiving the file in parts with the method of creating a self-extracting archive.
Right-click on the file, select the item WinRAR - Add to archive, and in the window at paragraph Divide into volumes in size (in bytes) prescribe the size of the archives. And on the right side, put a tick in front of the item Create SFX archive... Then click OK .
The self-extracting archive will be ready in parts.

In this case, you can also use the help of Winrar and try to restore it. To do this, run this program and find the damaged file. Select it and click the "Fix" button in the top panel, you can also recognize it by the image of the first-aid kit.

It is free, and working with it will not differ much from the previous example. In order to collect the archive, place all files in one folder, as is the case with WinRar. Then select the first file and press the right mouse button. A context menu will appear - select the 7-zip item in it, then "Unpack here", after which the archive will be merged.When working with multivolume archives, you should not make mistakes common to novice users. First of all, before the process of combining files, check if all parts are present. A distinctive feature of the last part is that its size will always be less than the size of the other archives. On this basis, you can easily determine the presence of all volumes. Also, if after unpacking you come across a file that has the iso extension, you should not unpack it, despite the fact that it looks like an archive - this is a special file that can be opened using programs that work with disk images.

Its choice depends on the purpose of dividing the files into fragments. Please note that the size is given in bytes, i.e. for installation maximum size in 50 MB, you need to enter the number 50,000.After preparing the parameters, click the Ok button. Wait for the required number of archives to be created. Use the same program to connect all the parts into a single whole.Right-click on the first fragment of the archive. Go to the 7-zip submenu and select "Extract files". In the new window, specify the directory into which this archive will be unpacked.

How to assemble an archive from parts?
On a forum or any other resource with a limited file attachment size, archives are often split into several parts for easy transfer. This practice is also widely spread when recording is required. large files to removable media.
In order to assemble an archive from parts, you need the WinRar program. If it is not yet installed on your computer, then download it from the Internet, and then start the installation process. You will need to follow the steps required by the wizard installer and perform file associations in order to get fast access to the program menu.
In order to create an archive yourself from parts, you need to open a folder with the desired file (if the file is not one, but several, then for convenience it is better to place them in the same directory). Right-click on the selected files or the folder containing them. In the WinRar menu, select the "Add to archive" item. Will appear small window... It is necessary to enter the name of the archive. If you want to send these files over the Internet, then the name of the archive is best entered in the Latin alphabet. On the adjacent tabs, you can configure the archive parameters. If necessary, you can set a password and encrypt the content. This is very convenient if the contents of this archive are intended for a specific person, but cannot be sent personally. If necessary, you can add files using the "Browse" button in the main tab.
The archive can be split into parts. The size of this part of the archive is indicated in bytes. In new versions of the program, it is already indicated possible variant the size of a part of the archive, it serves as a template for splitting. This is very convenient, especially if you need to burn it to floppy disk, CD or DVD, and so on.
After you have made sure that you have correctly configured all the parameters, click the "OK" button. It will not be superfluous to check, after creating the archive, whether everything is working correctly. To unzip the archive, select all parts and select "Unzip". After specifying the directories of the future location, extract the file. If possible, check its performance after unzipping.
When archiving files using WinRAR, you can change several options for creating an archive, including splitting it into parts. Let's show 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.
You should see a window with settings for archiving parameters. In its lower left area, find the inscription “ Divide into volumes by size».
Here you can choose what size 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 \u200b\u200bfrom the drop-down box - 5 MB, 100 MB, 700 MB, etc.
For example, we will choose 5 MB. To start archiving with division, press " OK».
In the folder next to source filesif you did not change the folder for saving this archive in the archive options, the parts of your split archive will appear.
All volumes will be of the selected size except for the last one - there will be how many will remain. 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 (17-5-5-5 \u003d 2).
