Score is corrupted and cannot be opened.

• Jul 23, 2025 - 04:24

Can someone please help me de-corrupt my score so I can re-open it on my laptop. I can't open it through the MuseScore studio itself or through the 'scores' files on File Explorer. I don't think I have any back-up scores either. I would extremely appreciate it!

Usually, musescore will automatically make backup scores for your scores. just find whatever the score is and after you found the .mscz find for the .mscz-backup (or whatever that filename is). Hope this helps. EDIT: musescore dont make backup files lol sorry

Anyways, do you remember how you made it? if you still then make it all over again. if you saved it to the internet musescore cloud you can open it from there i think, or if you made it public just open it because if its in public the score is probably saved in the database.

Ya that’s the problem - I only have it saved to my computer and not online. I could check if I do have a backup file anywhere - and if I don’t worse case I just restart but that will take me months again. But how do you find the .msczbackup it in file explorer for windows? Do you search it? I’m really confused, sorry :(

.mscbackup is a hidden folder in your “Scores” folder. Ask a search engine how to make hidden files and folders visible for your operating system.

In Windows, your files and backup files may be located in the following locations:

C:\Users\{YourUserAccount}\Documents\MuseScore4\Scores
C:\Users\{YourUserAccount}\Documents\MuseScore4\Scores\.mscbackup
C:\Users\{YourUserAccount}\Documents\MuseScore4\Cloud_Scores
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

Like ".mscbackup", "AppData" is also a hidden folder.

Ok nvm, I've found the .mscbackup file but all the icons and titles are faded. When I open any score in that file it says it cannot read the file. I clicked properties for the complete file and unchecked the hidden box as well as the read only box and it still shows that the files are faded. I'm guessing this is why I can't access my backup files either ...?

Ok so I renamed the file and it still was corrupted. I’ve also tried turning it into a zip file and it was invalid. Honestly I think my score completely screwed lol and I’ll prob have to restart my entire composition. Thank you guys for all the help that you could provide me with - I really apprech!

You cannot "decorrupt" this "score" since it is not a MuseScore file and is only a file full of zero-value bytes. You can open files such as this in a a moderately-advanced text editor program or with a hex editor program. The only safe backup is by saving the file with different names as you go and by copying the saved files to another location.
