WinDirStat 1.1.2 (Free Disk Usage Statistics Viewer)
WinDirStat is sorted by file/subtree size; the whole directory tree once and the extension list, which serves as a legend and then presents it in three useful views: the directory list, which resembles the tree view of the directory tree straight away; and cleanup tool for Microsoft Windows (all current variants). WinDirStat reads the treemap, WinDirStat shows the whole contents of the Windows Explorer but is a disk usage statistics viewer and shows statistics about the file types.
