WinDirStat:Windows Directory Statistics
WinDirStat (WDS) is a disk usage statistics viewer and cleanup tool for Windows. It shows disk, file and directory sizes in a treelist as well as graphically in a treemap, much like KDirStat or SequoiaView.

Features
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.
- Coupling. Select an item in the directory list: The treemap highlights it; and
vice versa. - Zooming.
- Built-in cleanup actions including Open, Show Properties, Delete.
- User-defined cleanups (command line based).
- Works with network drives and UNC paths.
- ‘Create disk usage report’ option.
- ‘Submit bug report/Feedback’ option.
- Online help.
- setup.exe.
- Language can be set to Czech, Dutch, Estonian, Finnish, German, English, Spanish, French, Hungarian, Italian, Polish and Russian.
