Cannot read file
Hello,
Last night I had been working on a score which I had nearly finished. I was saving it very often. Now, this morning, the file won't open. I get a message "Cannot read file C:/Users" etc. I tried to recover a backup copy, following the two sets of directions I found on this site.
I opened the first saved version (.filename.mscz,), which wasn't very useful because it only showed a very early save (not entirely useless; I guess I can start again from this point). The second method, C:\Users\\AppData\Local\MuseScore\MuseScore2\, only showed two options for the session, both of which were blank scores.
Do you know what has happened? I've accepted that this score is probably gone (unless someone else can recover it - I've added a link), so I am wondering if it would be best to save it privately online in the future? I really don't trust my computer anymore!

An MSCZ file is a regular ZIP archive and can be opened by any program that can read that format. Your file cannot be opened in the archive manager program on my system, so apparently it is corrupt at a pretty fundamental level, like if you had a disk failure while the file was being written. Wouldn't hurt to run disk diagnostics to see if there are bad sectors that need to be dealt with.
It's possible there exist some general purpose ZIP repair tools that could try to turn this back into a readable archive, but unfortunately, I suspect you are correct that you will most likely need to go back to that earlier backup. The autosave files are most commonly useful after an actual program crash, but that didn't happen here, so they were probably cleaned up when you closed the file.
The file is filled with 00's (zeros) after ~40%. I really doubt even a ZIP recovery would extract enough XML data to be useful.
