This is odd. Disk utility says that I'm using 180gb of data on my disk, yet when I add up all of the folders under my Hard Drive, they only add up to 99gb. THEN, if I get info on my Hard Drive itself, it also says it's using 180gb! Somewhere, I have 80gb that is just lazing around and taking up MY precious space. How can I search for the biggest FOLDERS, not just files, on my drive? Is there a way that maybe it got deleted but didn't free up space? If so, how can I get it back? Thanks.
