let me introduce you the situation.
I'm downloading a lot of videos on YouTube using batch.
Those appear as "video.mp4" in a folder named "20111212-Biloulette-la vidéo d'aujourd'hui", so as "Date-uploader-title". So i'd like to put tags in "video.mp4" using the name of the folder that way : %date%-%artist%-%title%.
How ? Because i can't find how to use the folder name instead of the file name.
