I am down to 45.65 of my 250GB Hard Drive. I don't see how I only have that little bit left. I opened Finder and click on Macintosh HD. There are 5 Folders...Applications, Library, System, User Guides And Information, and Users. I click on each folder and here is what Quicklook was telling me... Applications... 4.65GB Library... 9.14GB System... 4.65GB UG&I... 180.7MB Users... 84.11GB That rounds up to 103GB Where is the other over 100GB that it is saying is used at?
