Trying - again, to learn more about Microsoft Windows - noticed on a laptop that the s'posedly 80gig drive only had about 10% free.

Having sort of tried to find a command line equivalent of the 'nix 'du' command - and consequently given up, I eventually found a nice, small, uncomplicated little drive scanner that presents the space used in a basic yet insightful piechart.

The .exe is attached, as is the full .zip which also contains a registry hack and readme file.
