MP3Tag 2.59b copies entire folder during rename.
Here's the action: Format Value _DIRECTORY : D:\Music\%artist%\%album%\
I have an action that music to a folder based on the artist and album name, and it's supposed to copy the music files highlighted in mp3tag to a folder based on that metadata, instead it will copy the highlighted music, and EVERYTHING else in that folder, except subfolders.
