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 SII file may be unusually small compared to the original file. This suggests truncating the SII file contents when downloading or copying. Downloading the file again should fix the problem.
The most common cause here is computer viruses. 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 SII or the program directory. As a result of the scan, sometimes it is not possible to recover SII files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the SII files changes over time. These problems are known and are often very easy to fix using the software developers's website.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular SII file corruption.
The program can also signal the fact of encryption. The encrypted SII files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. These directories are write-protected to them and it's very hard to fix this problem. It is best to move SII to a different directory.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the SII file again. Some anti-virus or backup software may occupy the SII file for a certain period of time. If nothing helps, please reset the device.
