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).

Features

  • Three views: Directory Tree, Treemap, and Extension
  • Duplicate file detection
  • Built-in cleanup actions including Open, Delete, Show Properties
  • User-defined cleanup actions (command line based)

What's New

Even though it has been 19 years since the last official release, WinDirStat has continued to be a staple of many system administrators' and casual users' computer toolbelts. Some Windows alternatives have appeared over the years, but few have been completely free and even fewer have been opensource. About a year ago, I reached out to Oliver offering to get more involved with WinDirStat development. With his help, I am pleased to announce the release of WinDirStat 2.0.1.
