Corrupt Files

[Euphonium01]

I am a newbie on the Forum, but I have been using Finale a good few years. I have tried searching the Forum but cannot find an answer!
I had a drive with many Finale .mus and .musx files. I have recovered them but without their respective original file names (just numbers). When I try to open any of these files, I get the error message: Invalid file type, file 'D:\......... appears to be corrupt, attempting to continue, but resulting document may be unstable.' A few OK clicks later nothing opens, I am left with Finale Window opened with nothing showing.
I am certain this misfortune must have happened to other members ( and become as sickened as I feel). However, some members may have fixed it, or found a software solution to fix this... can anyone please help, I don't relish losing many years of work? I appreciate and thank any helpful replies.

Attach one of those files here and we can take a look.

Did the drive fail? Exactly what happened, and what did you do? Did you use some recovery software?
When a drive fails, it is imperative to stop using it immediately, before then applying recovery software. (Recovery is possible on hard drives, but almost impossible on SSDs.)

I don't relish losing many years of work.

I cannot over-emphasise the importance of keeping more than one copy (on separate devices) of ANY files that you want to keep. Files with no backup are waiting to be lost. I hope you are able to recover the data.

Most files were on an SSD unfortunately, I have a few that were on HDD but only a handful (about 7 or 8?).

I hoped there was some specialised software to recover files, but it would appear not. I have taken advice from Buon Tempi and created multiple copies of files. I am usually quite maticulous with my file storage, so this has never happened before, I guess I became too complacent and paid the penalty.

I will keep the corrupted files in a safe place in the hope someone does come up with a package to help clean them.

I had issues converting .MUS files to .MUSX. What worked for me was was firstly exporting them as *.MusicXML files then saving them to MUSX in the new version of Finale. The procedure scattered the fingering, articulations and custom lines, and took several weeks to correct as I have many files; but I managed to convert and save all my work.
