I can get rules to work on a folder, and I can get it to go into a folder and sub folders, but one thing I get stuck on is saying:
Delete this folder, unless it has a movie in it.
I see that you can't mix and match folder and file rules, (which would solve my problem)
...so what is the best way of saying:
Delete this folder, unless kind inside is movie.
Do I need two rules to do this?
