Hey
Well, my hard drive is quite small, on a laptop

only 70gb

and i have barely anything left, something like 10gb left,
i know i have 6gb of music, and that windows takes around 10gb, and on top of that, 10gb worth of programs. so that is about 26gb out of 60gb used, so where the hell is the rest of this data being taken up?!
So, im wondering, on my school computers, there is an alplication that shows you how much of your quota is being taken up in each folder, is there any program like this available for free? or do you know of anything that might be helpful in this situation?
Thanks
