Looking for a program

[Zkato]

A while ago (before I switched back to Mac), I was stumbling around the internet and I came across a program which showed a visual representation of the files in your hard drive.

Not quite sure if it was freeware.

Thanks for your help.

[EDIT]
Really sorry... Found it myself.

Its called GrandPerspective if you are interested.

Don't worry, I'm not a advertising bot.

There's another one called Disk Inventory X.
