Delete subdirectories

Hello Mr. Noodle.
Once again I need your help. I need to create a simple rule to delete empty subfolders or only with some log files within the directory downloads. I made several unsuccessful attempts

I thank you for your help.

Can you post what you tried so far?

First I created a rule for the folder contained in the directory downloads. In the sequel I made a rule to delete folders with less than 500 kb. Why does not work?

If you have those two rules and they are in that order, remember that only one of them can match the same folder by default. Because the first one matches ALL folders, it never gets to the second one. Try reordering them. Make sure to use the preview function (the "eye" button) to check your work.
