Generating previews deleted data?

Still trying to make sense of this.

  1. Clicked scene tab
  2. Filtered on a folder
  3. Select all
  4. Generate preview

I noticed nothing happened. Tried playing a video didn’t play tried going to the location in the file directory and it’s not there.

Struggling to see how i could select all but the files were never there. Luckily i made a backup of that very directory before running operations so nothing is lost I’m going to try again.

I’m new to this software but i’ve been able to categorize a lot of media without any big issue. I would check logs but I don’t think they’re enabled by default.
