Just a quick question. My PB's HD is 80gb. I have alot on it, but not this much... When I check my space left, I only have 2.1 gb left. When I check my HOME folder, that includes my Movies, Music, ect, it only shows that I have 30gb in there. So where is my other 40gb or so. Is there a program or app to show where all my hd space is going? Thanks
