OverDisk is a disk usage browser. It can be used to quickly find out how a partition's space is distributed among the file system hierarchy.
I've currently stopped working on it, due to a bug in the libraries of the original developing environment. However, I intend to move the project into another suite and incorporate more features from some other utilities I have. So, stay tuned... final version coming Real Soon Now™ ;)
In the meantime, you can download an alpha version, complete with installer/uninstaller and (slightly out-of-date) documentation. Note that this is pre-release software and represents work in progress. Nevertheless, I've been using it for quite some time now and the only problem is that it occasionally crashes after several refreshes. No serious system implications have been observed, especially on WinXP, which is a pretty robust OS! :)
