WinDirStat is a disk usage statistics viewer and cleanup tool for Microsoft Windows.

WinDirStat is a program that allows you to find drive space hogs at a glance. It achieves that by displaying a drive, drives or directories in a treemap that assigns bigger areas to bigger files and directories. Making those areas visually separate by coloring and other means allows you to see literally at a glance what the space hogs are and where to dig deeper.
The directory tree is simultaneously shown as a tree list and as a treemap. One can effortlessly gain an impression of the proportions on the drive(s).
