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.

    Big relief I was having hard time to find the directory consuming most space. This was exactly what I needed. Thank You.

    I have been using WinDirStat for years with good results. However, today Windows said I was almost out of space on my System disk (Samsung SSD 1 TB). I used WDS to look for the offending files and was surprised when there was a little over 300 GB difference between Windows report of space used and WDS report (yes the swap file and hibernate are included in both reports). I hope another user of WDS can suggest why there is such a large discrepancy between the Windows and WDS space utilization reports. Thanks in advance. Hmmm, no idea why, but Windows has found more free space and now the two are reporting about the same amount of used / free space. Would be nice if WDS compared what it found to what Windows is reporting and at least acknowledged the discrepancy, if/when it exists. Thanks everyone.

    Simple, fast, efficient. You get a great overview of what is taking up the most space, and can see what directories take up how much of your disk with ease.
