Looking for utility

I'd like to be able to see where most of my hard drive space is dedicated. I can always just right click a folder, properties to see the size, but I'd like to be able to do is, as an example, be at C:, see the folders by size, and then drill down. Preferably graphic VS number size, as I find graphics to be more intuitive.

Thanks,
Rob

TreeSize is just what you're looking for. I use it all the time and bought the pro version for work.
