Ok so i ran into a conundrum. I have a 120Gb HDD in my MBP and it's formatted size is 111.47Gb. The dilemma is, I have 62.56Gb left! My music folder is ~15Gb, Pictures are ~2Gb, Applications ~ 8Gb, and everything else is barely over 500Mb. How have I used 48.91Gb without knowing it. Tiger doesn't take up more than 20Gb right? Where the hell is my disk space going. And it decreases sometimes too without me knowing it (I think). What are some good, free, defragging utilities?
