I have looked everywhere to find this. Most YT videos are too complicated and are more complex than I need.
here is my scenario:
A folder with a given title. I need a rule that will simply rename the file to the Folder above. There are no sub folders and only one file in any given folder. The only thing I need to stress is that the renaming must not affect the extension.
So to clarify: I drop a file into a folder and the file is renamed to the folder it's in. But the extension remains unchanged.
I am pulling out my hair, trying to solve this. Well, what little hair I have left.

Kind Regards
