View that shows you a color-coded view of what’s using space. When you launch WinDirStat, you can tell it to scan all local drives, a single drive like your C: drive, or a specific folder on your computer.Īfter it finishes scanning, you’ll see three panes. On top, there’s a directory list that shows you the folders using the most space in descending order. Its interface allows you to see exactly what’s using space on your hard drive at a glance. WinDirStat is our preferred tool, and it’s probably all you’ll need.
