WinDirStat (Windows Directory Statistics) is a disk usage statistics viewer and cleanup tool for Windows. On start up, WinDirStat reads the whole directory tree once and then presents it in three useful views: - The directory list, which resembles the tree view of the Windows Explorer but is sorted by file/subtree size, - The treemap, which shows the whole contents of the directory tree straight away, - The extension list, which serves as a legend and shows statistics about the file types. Visit the WinDirStat blog for more up-to-date information about the program. Note: If you are looking for an alternative to WinDirStat for Linux, then you are looking for KDirStat (apt-get install kdirstat on Debian-derivatives), and the alternative to WinDirStat for MacOS X is Disk Inventory X or GrandPerspective.
