I've written a rule that checks for subfolders named "Output" that have a size greater than 1 byte. I'd now like Hazel to move the contents (including other subfolders) of the Output folder to the Trash, but I'm not exactly sure how to do that, without also moving "Output" to the Trash as well.
Also, is there a better way to determine if a folder is empty, than using size greater than 1 byte?
