WinDirStat – Visual Disk Analyzer and Cleanup for Windows

Here's what you get when you fire it up:

A detailed directory tree, like what you'd see in Windows Explorer, but sorted by how much space each folder or file is taking up.

A colorful treemap that visualizes your entire drive as a collection of rectangles, where each block's size reflects how big the file is.

An extension list that shows you what types of files (like .mp4, .zip, .exe) are hogging the most space.

The treemap view is where WinDirStat shines. Every file is represented as a colored block, grouped into larger rectangles representing folders. So you can quickly spot if, say, your old video editing project or that Steam games folder is bloated. Each color on the map corresponds to a file type, making it easier to distinguish between media files, system junk, documents, and more.

Who's WinDirStat For?

If you've ever run out of space on your SSD or felt like your hard drive filled up overnight, WinDirStat is an easy way to get answers fast. It's especially useful for IT pros, system admins, or anyone managing shared PCs or network drives. You can use it before a cleanup to find the real space-wasters—or just to keep tabs on what your storage is being used for.

Geek Verdict

That treemap might look like a digital quilt at first glance, but once you get used to it, you'll grow to love it. It's perfect for cleaning the house without guessing.
