I did search, because I recalled seeing a thread on this in the past, but mostly found threads about upgrading when you run out of space. I have an 80 gig harddrive, but it's almost full. I go through my folders, and see that music is about 7 gigs, photos is about 7 gigs, applications folder is 5 gigs, documents folder is 1 gig....at most I can account for perhaps 25 gigs of data. Where is the other 40 gigs coming from? Trash is emptied. Is there some simple way to list folders based on size or something to figure out what is taking up my harddrive space?
