Is there a way to recover files that were accidentally deleted when a DLU user logged out, i.e., files created or that were already there under that user's "user"? If there is a "cache", where is the cache and is it accessible from the regular user?

I have two users at the moment that were accidentally setup with a DLU that made them administrators. When they logged out earlier today there user was deleted and now all files are gone but the directory structure is still there which is why it is confusing.

Would data recovery software be able to undelete the lost files?

Thank you!
