The operating system may be infected with a computer virus. A quick virus scan using an up-to-date antivirus program should clear up any doubts.

As a result of the scan, sometimes it is not possible to recover GM3 files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of GM3 file may not always be supported by the latest software version. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged GM3 files.
The program indicates that the file is encrypted or corrupted. The encrypted file GM3 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.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. The problem is only writing to the file, not reading it. Copying the GM3 file to another location will fix the problem.
This can happen on a file that does not support multiple access. In this case, the GM3 file is blocked by the first application to open it. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the GM3 file again. However, some background programs may block the GM3 file while scanning. If the problem persists, restart the machine.
