Look at that pretty harddisk!
I was running low on disk space for my main drive and needed to do some cleanup. Years ago I started to use WinDirStat and I’m still using it. This neat little application will scan your whole harddisk and will show you where you are burning the most disk space. Once all files and directories are scanned you get a treemap view of all files on your system. The larger a certain colored area, the more disk-space is consumed by that portion of your file system. Click on a color and it will tell what files are responsible for that color. Very easy to spot areas that can be cleaned up quickly to free up disk space.
Try th Dirlot - http://soft.km.ua/soft/dirlot/index.en.html. Maybe it is not so motley but definitely simler аnd smaller one.
