Corrupted MuseScore 4 File (cannot open)

Size, as they say, isn't everything. The file contains only zeros - 41, 856 or so zero-value bytes.

I opened the file with a hex editor - I used Bless in ubuntu but others are available for Windows, Mac.

Folders where you can search for musescore files (Windows) if you did not save one:

• C:\Users\{YourUserAccount}\AppData\Local\MuseScore\MuseScore4
• C:\Users\{YourUserAccount}\AppData\Local\MuseScore\MuseScore4\cloud_scores
• C:\Users\{YourUserAccount}\AppData\Local\MuseScore\MuseScore4\cloud_scores\.mscbackup
• C:\Users\{YourUserAccount}\Documents\MuseScore4\Scores
• C:\Users\{YourUserAccount}\Documents\MuseScore4\Scores\.mscbackup
• C:\Users\{YourUserAccount}\Documents\MuseScore4\Cloud Scores

This list may be incomplete or incorrect though
If you find something interesting, copy that file to another location and open from that new location

It should be added that in "AppData" the files have cryptic names, but already with the extension mscz. Orientate yourself by the date of saving.
