HDD Allocation program

[Spike88]

My HDD has gotten to the point where I need to find out where all my space has gone, and possibly clear some of it up.

I used to use this program that scanned your computer and then let you filter by which folders had the biggest memory contents. Anyone know of programs like this?

I like WinDirStat (http://windirstat.info/) for this kind of thing.

Disk Cleanup in System Tools is also good for clearing out old System Restore points and such.
