I dont know if this is the right place for this but...here goes.
I made a mistake I think when I imported my music into banshee I went into pref. and selected copy media files when importing and now my music library is 13.3 gigs.
Whats annoying is I just switched to ubuntu and I have an 80gb drive specifically for media documents etc and when I switched I managed to duplicate it all...going through 13GB is kind of a hassle is there a way to make a playlist or something in terminal I can do to remove the duplicates?
