Software to tell me which folders are using up the most space?

[Rip The Jacker]

About a week ago my HDD had 106GB in free space, and now I'm at 93.1GB of free space. =/

I don't remember downloading much, where the hell does all that space go? =/

Is there an app that'll kinda tell me what folders are taking up how much space? I wonder if there are some left often junk folders or anything like that... just so I have a better idea of how much I lose space and why...

Theres actually a program called XP Smoker which I downloaded recently that does have this feature in it. It tells you which programs and which folders take up the most space on your computer and how much. It also comes with other tweaks that you perform to Windows to speed up ur comp etc..

WareSoft XP Smoker 5.0 Pro is the version I downloaded.

SequoiaView, excellent progam... (enable the colour setting to see each type of file, as shown in the top screen cap... highly recommended).

I love this app.
Such a cool way to visualize the HDD and it's contents.
