my musescore 4 crashed when I had a score I had just made and didn't save while i had another open in a different window, i closed both and it would usually say that it crashed unexpectedly, but it didn't and now my score is gone. What do I do?

I was making a score, when all of the sudden my MuseScore 4 crashed on me and I just got finished writing the score. It crashed before I was able to save, and so it didn't save. Is there anything I can do about this?


If it was an existing score, then you can just reopen it and MuseScore will use the auto-save version if present.

If it was a newly created score, then you might be able to find an auto-save version called new_project.mscz in MuseScore's data folders, for which the location depends on the OS:
- macOS: in Finder, press Cmd+Shift+G and enter ~/Library/Application Support/MuseScore/MuseScore4
- Windows: in Explorer, enter the following in the address bar: %LOCALAPPDATA%\MuseScore\MuseScore4
- Linux: ~/.local/share/MuseScore/MuseScore

If this folder contains indeed a file called new_project.mscz, then this might be an autosave version of the lost file. Open it, and immediately save it to a safe location using "Save as…", so that you won't lose it again.

Same thing just happened to me! It is my first time using MuseScore and I was working on my score for 1.5 days. I had somehow assumed, it was saving my work behind the scenes periodically and I didn't hit Save. Now my entire work is gone! The temporary file is not in ~/Library/Application Support/MuseScore/MuseScore4. Arrghh! MuseScore should fix this such that the temporary file cannot disappear!
