Program that breaks down C: usage

i used to have a program that showed me which folders had large files in them. i cant remember its name... it even made a pie chart i think. does anyone know the name of this freeware?

 

i found a good substitute using google, "TreeSize Free" - - its not what i remember having, but it gets the job done. i was surprised to see that there were so many gigs wasting away in my temporary internet files folder. it seems like every time i watched a video online, it was saving a copy in there?! is there a way to stop that from happening, so i dont have to delete all of it after it builds up?

 

Start/All Programs/Accessories/System Tools/Scheduled Tasks ... Disk Cleanup Schedule it to your convenience ....

That's the XP path , would imagine it's similar in Vista
