Hey ppls

I seem to be running out of space on my 60 gig empeg. yet my friend has the same exact mp3's and space and he has more than 2 gigs left and i only have 1 gig. so i decided to go through the bbs and look for anything that could help me. all i found was to do a advance search on refs = 0. so i did that and I have 1175 items that come up - so my question is should I be deleting these 1175? and if i delete these will anything happen that will affect the playlists?
