Programs to open R1 file

Remember to download programs supporting R1 files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of RARLAB RAR with R1 files

If the application is or has been freshly installed, but the R1 file still does not use the RARLAB RAR program, it means no association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location.

Step 3. Update RARLAB RAR to the latest version

If, however, after binding RARLAB RAR with WinRAR Multi-Volume Archive Part 1 there were still problems, you should update the program to the latest version.

Step 4. Check for the following problems with the R1 file

The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:

Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the R1 file. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the R1 file that we want to open. Sometimes virus-infected R1 files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the R1 files changes over time. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged R1 files.
The program indicates that the file is encrypted or corrupted. The encrypted R1 files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. Copying the R1 file to another location will fix the problem.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the R1 file again. Some anti-virus or backup software may occupy the R1 file for a certain period of time. If this does not work either, restart the device.
