Can't recover lost score after crash

• Oct 17, 2016 - 16:04

Alright, so about a week ago I was working on a score that I had been doing for about two months now, and musescore crashes, and the next time I go to open up my score, it says that it can't read the file.
So I go to https://musescore.org/en/node/52116 and try both of the suggestions, and after a bit of time finally figured out how to show hidden files, only to find that some of my other scores have backups made, whereas the one that crashed does not have a backup made. After that I try the second suggestion about autosaves and go to that folder. I end up finding several autosaves of this particular score, but none of them are current. For example, it was about 4 minutes long at the time (can't remember amount of measures) and all of the autosaves were all the way back when I only had just a few measures.

So if any of you have ideas or might know what I'm missing, I really appreciate your feedback.

Try to open the the corrupt file with an archive program (like 7zip). In some cases it's possible to extract the mscx file.

Musescore has two native formats (extensions of a file): mscz and mscx.

https://musescore.org/en/handbook/file-formats-0#musescore-native-format

A mscz file is a zip-compressed Version of the uncompressed mscx-format.

In a few similar cases as you described it was possible to extract the mscx file from the corupted mscz file. Open the corrupted file with 7zip or a similar program and have a look if it contains a mscx file.

You can also attach the corrupt score.

Alright, so I got 7zx and I opened the file with that and it creates a mscz.7z.001, which I'm not really sure what to do with, but I just opened that and it created the same file that I originally had.

You've to look into the content of the mscz file (maybe rename the "name of file".mscz file before into "name of file".zip) , not create a further zip-file.

But the easiest way would be you would attach the corrupted file in your reply (see below on the side of your reply), so that someone in the community can have a look, if there is anything repairable.

Sorry, but this file is so corrupt, that it isn't repairable. Only the size of 0 bytes indicates, that it's an empty file with no content.

So your only chance would be to search again and again for a file of an autosaved version in:

~/Library/Application Support/MuseScore/MuseScore2/
(open each file in that directory)

or for a "last saved"-version (with a comma at the end of the file) in your directory where you normally save your scores

I'm aware, you've already done it, but I'm afraid there's no other way.

Unfortunately that file is completely empty, nothing to recover from that. There was a bug in earlier versions of MuseScore that could in very rare cases leave you with an empty file like this after a crash, but it's been fixed for 2.0.3, so do be sure to update so this doesn't happen again. meanwhile, I'd turn your attention back to finding the backup that has to exist unless you literally never closed the file for two months.

If you had been working on that score for months, there has to be a backup - well, unless you literally left your computer on and booted with MuseScore and that score laoded the whole time and never closed anything. There should be a backup showing the state of the file the last time you opened it. Maybe you could find someone with more computer expertise to help you locate it?
