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. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file VLZ or the program directory. However, remember that not every infected VLZ file can be recovered, so it is important to take care of regular backups.
A typical compatibility error - the program does not support the older version of the VLZ file. 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 this. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular VLZ file corruption.

This can happen on a file that does not support multiple access. Some file types can only be opened in one program at a time. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the VLZ file for a certain period of time. If nothing helps, please reset the device.
