I've had a major clear out of my itunes library, deleting about 5 gig of music, but my itunes folder in 'my music' on my C drive is still showing everything i've ever had, eating up loads of memory space.
Is there any way of quickly just deleting the unused music, leaving my itunes playlists intact?
The only way I can see to do it is to go through the folder and manually delete ach album/artist thats no longer in itunes??

Cheers
