Is there a way to repair a corrupted AUP3 file?

This is a duplicate post that has been addressed here: Audacity failed to read in from Drive D.

Windows 10
Audacity 3.2.1
Link to wetransfer aup3 file ( aprox 500 mb)

Good morning,
Can someone help me and check if my .aup3 file is recoverable?
is a 25-minute audio recording for an educational film for children…
Before turning it off, I saved the project as , and save it a second time to be sure. After restarting the computer, the file cannot be opened.

I read the entire topic from start to finish and looked at the link, but unfortunately I don’t understand how to use these files and information

Greetings from Poland
my mail

See the first post here: Corrupt or Otherwise Broken Audacity Project Recovery

I did it step by step and I received a file that weighs 320kb and is empty


320kb is the size of an empty project database. Post the link to your file.

So I took at look at the .aup3 your posted (Note for others - I am not repairing theses files any more), but I wanted to salute you for efforts and to confirm your results.

So the bad news is there is nothing in your file. I don’t mean nothing in your file to rescue, I mean nothing in your file at all - just binary zeros - as far as I could see, anyway.

And no, I have no idea how or why this could have happened. :frowning_face:

Thank you, despite the bad news, for your time.
After a week, I decided to record the material again. I’ve learned a lesson for the future. Thank you very much for your help and time.
All the best to you
