**SOLVED** How to fix a corrupted file? (Musescore 4)
Ok so, I had a .mscz file saved in MS3 before converting it to MS4. Apparently, it corrupted while I was trying to make edits to fix a bunch of piano measures that was acting a bit funky with musesounds. I should mention this is a BIG concert band piece (full instrumentation w/ piano and 5 percussion parts). How do I uncorrupt a file because it won't upload to the website anymore?

Try this: if MU4 opens the file export it as Musicxml. Open it with 3.6.2 to find and correct the corrupted measures. Save, open with MU4. It doesn't necessarily work though.

Another approach... without using the MusicXML conversion.
Okay, so you have a MuseScore 4 file: "BIG concert band piece.mscz" which has corruptions.
The ".mscz" file extension denotes a compressed file. Use a software like 7-Zip to decompress. (Depending on which software you use, you may need to re-name the ".mscz" file suffix to ".zip")
In the newly uncompressed folder look for "BIG concert band piece.mscx" - notice the .mscx file extension. Open this "BIG concert band piece.mscx" in MuseScore 4 and see if it is corruption free and usable.
If not, open "BIG concert band piece.mscx" in MuseScore3, which will protest, but press 'Ignore'. You should now have your score opened in MuseScore 3. Save this as a MuseScore 3 file (.mscz) and close it. Then re-open it in MuseScore 3 to "show" any corruption(s) - for example;
Measure 52, staff 1 incomplete. Expected: 4/4; Found: 0/1
Measure 53, staff 1 incomplete. Expected: 4/4; Found: 0/1
Measure 54, staff 1 incomplete. Expected: 4/4; Found: 15/8
MuseScore 3 allows to display a list of any corruption(s) it finds. MuseScore 4 does not.
You can make the repairs in MuseScore 3, then save the repaired score. Finally, if desired, open the repaired score in MuseScore 4 and save it there.

well looks like that method worked without having to use musescore 3, thanks! also is it possible for me to upload the .mscx file alone or do i have to convert it back to .mscz?

nevermind i found a way, thanks for sharing this tip!

"MuseScore 3 allows to display a list of any corruption(s) it finds. MuseScore 4 does not."
Do you know why? That seems odd.
I have a corrupted file but the things is, I started it in MuseScore 4 so I may have a slightly different issue. I'd like to diagnose my corruption and fix it instead of just having to start over.
EDIT
Never mind I tried your approach again more carefully and it worked. Still odd though that MuseScore 4 doesn't have its own "Show Details".
Thanks for the help!

Hello,
I was directed to this solution a few days ago with regard to a file I had converted from its original working file in Muscore 3, into Muscore 4. The consequent file immediately reported corruption and yet would not export to an XML due to a crash that inevitably occurred at export. Now, I have tried the work around above to attempt to open the file as .mscx in MS3, but I receive the following error:
"Cannot read file /Users/kokichi/Desktop/NAE/NAE PHASE 2/SCORES - MUSIC/010 - SHUGOSHIN/Nov2022Shugoshin_CompactMS4/Nov2022Shugoshin_CompactMS4.mscx:

I am nonplussed! Please help!

Open this in MuseScore 3 where you can 'Show Details' and then fix the corruptions:

My post above:
https://musescore.org/en/node/341420#comment-1163408
explains about unzipping the MuseScore 4 ".mscz" file to extract the ".mscx" file. The ".mscx" file can be opened in MuseScore 3, which will protest about it being from a newer version. Pressing 'Ignore' will open it in MuseScore 3. If this score is now saved in MuseScore 3 (no longer branded as MuseScore 4) and then re-opened in MuseScore 3 the 'Show Details' button will become available if any corruptions exist.
(MuseScore 4 does not allow to show corruptions.)

I'm having similar problems with a score I've been working on. I tried what you did but opening it in musescore 3 (both .mscz & .mscx) crash the app, so I can't save it into musescore 3 or even export it as MusicXML

Hello,
I've tried everything mentioned here and still can't find a way to fix this score.
To find the problem try making a change in any part in m91, and then try to save. This was created in MS 1 or 2 a long time ago. I've also tried deleting measures, working my way back from m90 to m80 and then adding measures only to have corruptions again.
What should I do?
Thanks

Holy cow, how did you do that?!
I just tested it quickly by modifying the Mark Tree in m91 which was causing error messages before when trying to save. Haven't gotten into it fully yet, but on first try...YES!
Please let me know what you did as I sometimes get errors on the 3rd movement, too.
Thanks!

For the record, in 4.0.2 that original opens with no corruptions reported. But had there been corruptions, the same techniques that worked in MU3 would work directly in MU4 as well. It was only in the original 4.0 and 4.0.1 where exporting to MusicXML and opening MU3 would be necessary just to see the corruption details.

Thanks @shoichi and Marc!
When the original score is first opened, everything is fine. I could change stuff in almost any measure before m91 and save with no problems. It was only if I tried to change anything in m91, and MAYBE after - didn't experiment much, that corruptions happened and the corruptions dialogue box popped up.
Think the corruptions were caused by there being a 6-tuplet in the Mark Tree, and an instrument change from English Horn (now Italian-ized to Oboe Barocco! Love it.) to Oboe. For some reason with that instrument change it created key signatures in every staff that couldn't be deleted.
What a huge relief, thank you all.

Thank you. This worked well for me - ie opening the .mscx file in MuseScore 3. The problem might have originally been caused by starting the project in a well-known commercial notation software and then transferring via .musicxml.

Hello this didn't work for me. Can you try to fix mine please?
In reply to Another approach... without… by Jm6stringer
Thank you! Had this exact issue. But I could not "repair" the 9/8 in my staff 1. I would never have even located it without your guidance to Musescore 3!) My "fix" was to delete the corrupted measure, then add a blank measure and repopulate it. Basically cut-n-paste for all staffs except staff 1which I manually edited. Tiny bit of tidying and I'm recovered. Big thank you to this forum!
MUSESCORE - Please fix this! My repair was straightforward, but I spent more than an hour figuring it out. All we really need is a version 3 diagnostic to locate where the issue is located. Perhaps a more complete diagnostic. And leave the diagnostic there after you address the periodic crashes that seem to lead us down this path. Thank you!

That diagnostic is back with 4.0.2

Another method that works for me is the backup file. Just check this for how you can recover autosaved or previous version of your score.

Actually not, I was about to fix the score by this morning but unfortunately I cannot open the score anymore and maybe that also became one factor why the score became corrupted. Anyways, I can already open the file, thank you so much!
All of my muscore 3 files were on my onedrive file system. I just received my new windows 11 laptop today so I wanted to see if the stuttering on Version 4 was gone with the 16GB. Every file I try to open with Version 4 is corrupted. I thought ok maybe it is windows 11 so I downloaded muscore 3 and tried to open my files from my old laptop which were saved on onedrove. Every file version 3 file I tried to open with Musescore 3 was again corrupted. I then tried to open the files with Muscore version 3 & 4 on my previous laptop and the opened file. I am at a loss. Any suggestions?

I figured out why I was having a problem. Windows 11 does not have onedrive built in. You have to download it, install it and start it to access files on one drive. Hope this helps someone else.

Okay, so if it worked perfectly, why the further need to post anything here?
On the other hand, if you need to post something, forget the uncompressed version (since it's too big) and attach the .mscz (compressed) file. We can unzip it ourselves.

I also have the same problem with the attached file. It was written in MS4. The system crashed and when I try to reopen the file I get the message that the file is corrupted. Unzipping the file didn't succeed nor import the file in MS3. Can you please help me to recover my data. Thank you!

a) that Glasul_VI_papadic1.mscx really is a Glasul_VI_papadic1.mscz, i.e. a ZIP archive and b) it is pretty empty, beyond repair

So instead of trying to repair that file, instead grab the backup file (in a hidden "mscbackup" folder underneath where the score itself is saved.
