All collection.media files disappeared

Hello. I went to study Anki the other day and it was fine.

Then today I opened anki and it said all my decks were gone.
I opened the folder ankidata\User 1\collection.media and it was completely empty. I had probably over 20,000 sounds files in here. At least 2 GB of files.
They are all gone. Every single one.

I went into Anki and restored my backup from User 1\backups. All the cards are good. Just the media all went poof. I downloaded Recuva and it cannot find any files related to anki (MP3) etc.

I had " synchronize audio and images too " unchecked but I just realized i had periodically sync media" checked.


Check media reports Missing files: ⁨23150⁩
Ankiweb says " Unused Media
You have 1163.04MB of media stored in your account"

Any idea what happened?

*EDIT
Ok I figured it out: Windows must of shutdown while anki was open or synching or something and took all the files and moved them to C:\found.000 C:\found.001 etc. I guess that’s check disk saying the files got corrupt. But I am recovering them a program called Wizfile.
They seem to be OK.
