my friend has a completely unorganized mess of mp3s on his comp. first, he has 4 directories of mp3s, which are deep inside other directory structures, then he has hundreds, maybe thousands of mp3s he doesn't even use, because he just downloads tons and then only loads the specific ones he wants into his playlist. What I want to do is put all his mp3s in 1 folder and delete all the ones he doesn't have on his playlist. Is there a program or winamp plugin that can delete all mp3s except the ones that are on the playlist.
