Backup file created when deleting multiple books from library??

[MrJamesEMcBride]

A long while back, while deleting books from my library that seemed to be duplicates, it seemed that if I deleted a lot of books at once, a file was being created that seemed to be a way to undo the deletion if I needed to. I think the word 'delete' was in the filename, but I cannot remember. I thought I remembered those files being created in the root folder of the drive containing the Calibre library, but I am not sure of that.

The reason that I am asking about this is that just recently I was deleting dupes again and I am NOT seeing those files that I remember being created before, and I am wondering why.

Does Calibre have a setting somewhere that would cause something like that to happen, where it would create an "undo file" of some sort when a large number of books are deleted at once?

I am wondering if it was some kind of 3rd party tool that was doing that previously.
