Where's my space?

WinDirStat is a disk usage statistics viewer and cleanup tool for Microsoft Windows. That's the official line from their website. What the utility does is give you a picture of the files on your hard from a perspective you may have never seen.

Files are color-coded by file type and sized according to file size. This presents an immediate visual representation of what is taking up all the space on your hard drive. Is it all those music downloads? Or maybe the movies you ripped are starting to add up.
