Cleaning up your hard drive!
This is a great tip that was submitted anonymously. It is a free application called WhatSize and it shows you exactly what is taking up space on your hard drive. You can very quickly browse through your hard drive and see useless files. After months of intense usage of your computer, it is incredible to see how the hard drive fills up with useless stuff. I wasn't sure how well the application would help clear up space, but it is incredible. Download here on MacUpdate.
