Software notes

The Bottom Line: Every Windows user eventually faces the mystery of the vanishing gigabyte, and WinDirStat solves it with a picture. The treemap — that colorful mosaic where a single bloated video file glares at you as a giant rectangle — communicates in one glance what folder trees take minutes to convey. Click the rectangle, find the culprit, reclaim your space. It is visualization doing exactly what visualization should do. It is old, slow on huge drives, and cannot delete anything itself — WizTree beats it on scan speed, and you will do the actual cleanup in Explorer. But old does not mean obsolete: the treemap remains the fastest route from “my drive is full” to “there it is.” For a free, safe, portable diagnostic that has answered this question for nearly twenty years, WinDirStat earns its permanent place. The extension list is the treemap’s quiet partner: it shows which file types consume your drive in aggregate, instantly revealing that videos eat 60% or that a forgotten backup folder holds 200GB of duplicates. System administrators have used it for decades to explain disk-full crises with a single screenshot — no technical vocabulary required. It will not clean anything for you, and that is deliberate: diagnosis and treatment are separate jobs. For the diagnosis half, nothing free has ever communicated faster.

Features

Free and open source under GPL-3.0 — the classic answer to “where did my disk space go.”
The treemap visualizes disk usage instantly: giant rectangles are your space hogs, no interpretation needed.
Three synchronized views — directory tree, extension stats, treemap — cross-reference each other on click.
Read-only by design: it analyzes but never deletes, so exploring is completely safe.
Tiny, portable, and honest — does one job with zero bloat or upsells.

Considerations

The project is effectively dormant — version 1.1.2 dates to 2007, with only community builds keeping it alive on modern Windows.
Scanning very large or network drives is slow, and the treemap can take a while to render on huge file sets.
The interface is dated and offers no cleanup actions itself; you identify the hogs, then delete them manually elsewhere.

About & Overview: WinDirStat Disk Usage for Windows PC

WinDirStat (Windows Directory Statistics) is a free, open-source disk usage visualizer that shows exactly what is eating your drive. Licensed under GPL-3.0, it scans a drive and presents three synchronized views: a directory tree sorted by size, an extension breakdown, and the famous treemap — a mosaic where each file is a rectangle sized by its footprint, so space hogs scream at you visually. Click a giant rectangle and the tree jumps to the culprit. It has been at version 1.1.2 since 2007 and the original project is dormant, yet it remains the clearest answer to “where did my disk space go,” kept working on modern Windows by the community. For the eternal mystery of the shrinking C: drive, nothing communicates faster than its treemap.

Frequently Asked Questions & Verification Guide

Is WinDirStat free?

Yes. WinDirStat is free and open source under the GNU General Public License v3. There are no paid versions.

How do I read the treemap?

Each rectangle is a file, sized by how much space it uses and colored by type. Big rectangles are your space hogs — click one and the directory tree shows you exactly where it lives.

Can WinDirStat delete files for me?

No. WinDirStat only shows you what is using space; deleting is up to you (in Explorer or your tool of choice). That read-only design is a safety feature — it cannot nuke anything by itself.

WinDirStat or WizTree?

WinDirStat's treemap remains unmatched for instantly spotting space hogs visually. WizTree is dramatically faster at scanning (it reads the NTFS master file table directly) with a similar treemap. For huge drives choose WizTree's speed; for the classic visual answer, WinDirStat still delights.
