Step 2. Create association of WinRAR with R81 files

If the application is or has been freshly installed, but the R81 file still does not use the WinRAR program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Changes can be made using the "Change" button. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the WinRAR application as the default for handling the R81 file.

Step 3. Update WinRAR to the latest version

The fault may also lie with the WinRAR program, it is possible that RAR Compressed Formats From A Multi-volume Archive requires a newer version of the program. This can be done using the application (if it provides such options) or from the win.rar GmbH website and install the latest version.

Step 4. Check for the following problems with the R81 file

Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:

The R81 file may be unusually small compared to the original file. This is most often caused by a problem while downloading the R81 file. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the R81 file that we want to open. However, remember that not every infected R81 file can be recovered, so it is important to take care of regular backups.
Older version of R81 file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular R81 file corruption. The easiest way is to restore the file from a backup, if there is one, or contact N/A
When reading, a message appears that the file was encrypted or corrupted. The encrypted file R81 except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. If possible, you can try to move the R81 file to another location.
This can happen on a file that does not support multiple access. In this case, the R81 file is blocked by the first application to open it. Closing other programs should help. If the error persists after closing other programs, wait for a while. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If this does not work either, restart the device.
