What is RAR file?

Files with the .RAR extension contain data archives compressed with a proprietary algorithm. This format was developed in its initial version in the year 1993, by a Russian programmer – Eugene Roshal, and currently it is being developed along with the WinRAR software.

It provides a high level compression and supports many additional functionalities, such as:

  • Retrieving data after an error, using the REV backup files,
  • Dividing large archives into several smaller ones – using a complex extension,
  • AES encryption of an archive,
  • CRC32 checksums and 256-bit BLAKE2 hash files.

Restrictions regarding RAR archives

RAR archives are created only with the graphic interface WinRAR software for Microsoft Windows system, and in a RAR console program in other platforms. There are also applications which have an agreement of the owner of the rights toward the proprietary format. It is different in case of unpacking the files – the source code is available for use, but with a restriction regarding back-engineering its source code. Not all versions of RAR format are backward compatible, therefore, sometimes the program will not be able to unpack some of the files with this extension.

When you install one of the applications from the list of programs that you found here, you should be able to open or edit the file with the RAR extension without any issue. However, if you still have problems with this, you may use the option of RAR file conversion to a different format.

What else may cause problems?

There can be more reasons which determine that you are not able to open the RAR file (apart from the lack of the proper application installed).

First - the RAR file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the RAR file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the RAR file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the RAR file has not been completed and it cannot be opened properly).
