WDUsage is a small tool based on ideas of WinDirUsage (by Kevin Routley). It can be used to visualize the disk or directory usage for disks and shares. The distribution of disk space usage is shown in a pie-chart and sorted in a list. The unit for disk space (B, KB, MB, GB, TB) could be easily changed. Also useful for Windows PE.
This tool was improved by quality inspection and ideas from my colleague Andreas Tranquillini. Thank you Andreas !
