Camera raw CLOSED, did I lose the project?

[Lucas_Nunes0]

I was editing about 800 photos in camera raw and overnight my computer shut down, consequently, photoshop closed, I tried to open the same files again and they are no longer edited.

Can I recover these files already edited somehow? or at least activate something autosave in case it happens again?

Wow, 800 documents at the same time in ACR? You are brave ( Lightroom Classic, better product for that).

To answer your question, sounds like you lost the edits, there is nothing you can recover I'm sorry to report.

Indeed. If you're going to do this again, get Lightroom, it's designed to handle this. ACR isn't.
