Diskaroo vs WinDirStat
Looking for a WinDirStat alternative? Here's an honest Diskaroo vs WinDirStat comparison. WinDirStat is free, open-source, and the OG Windows treemap that's helped people clean up disks for two decades. Diskaroo vs WinDirStat only makes sense if you also use a Mac, want byte-exact duplicate detection, or want a modern UI with active development — Diskaroo costs money, WinDirStat doesn't, and the page below is honest about which one fits which buyer.
| At a glance | Diskaroo | WinDirStat |
|---|---|---|
| Entry price | $2.99/mo | Free |
| Most popular plan | $14.99/yr | Free |
| Lifetime license | $19.99 (Mac + Windows) | Free (open source, GPLv2) |
| Platforms | Mac · Windows | Windows |
Pick WinDirStat if
- ·Free forever — open-source under GPLv2, no purchase, no account, no subscription, no upsell of any kind.
- ·Two decades on Windows. WinDirStat predates most of the category and has been the default 'how do I see what's eating my disk' answer for a generation of Windows users.
- ·Tiny footprint — installs in seconds, runs on essentially anything Windows ever shipped, including older machines where modern .NET apps feel heavy.
- ·Source code is auditable. For users in regulated environments who can't run un-inspectable closed-source utilities on production drives, that matters.
- ·No commercial-vs-personal license question. WinDirStat is free for any use; you don't have to think about whether your scan counts as 'business.'
Pick Diskaroo if
- +One purchase covers Mac and Windows. WinDirStat is Windows-only, so a household with both desktops needs a second tool for the Mac side. Diskaroo is the same app on both.
- +Byte-exact duplicate detection — three-pass strategy (group by size, then a 64 KB partial hash, then full-file hash) so a flagged duplicate is identical down to the byte. WinDirStat doesn't ship duplicate detection at all.
- +Active development — Diskaroo ships regular updates with auto-update built in. WinDirStat's release cadence has been intermittent for years; modern features like high-DPI polish and dark-mode UI lag.
- +Modern collector tray — stage files from multiple folders before deleting anything, review the whole batch in one place, then send to trash in one action. WinDirStat works file-by-file in classic Explorer style.
- +Native treemap with smooth zoom and breadcrumbs. WinDirStat's treemap is functional but visually dense and doesn't drill in cleanly the way a modern visualizer does.

Bottom line
WinDirStat is the OG, and I'm not going to pretend a $19.99 utility beats free open-source on price. If you're Windows-only, on a tight budget, and the WinDirStat UI doesn't bother you, just download WinDirStat. It works, it's free, the source is auditable, and millions of people have used it without complaint. Diskaroo only makes sense if you also use a Mac (one license covers both desktops), if you've ever had to hunt down duplicate files manually and want a tool that does it in three deterministic passes, or if you want a modern UI with active development. That's the buyer for Diskaroo. Everyone else, get WinDirStat.
FAQ
Is WinDirStat really free?+
Yes. WinDirStat is GPLv2 open source. No paid tier, no subscription, no telemetry upsell. Diskaroo is a commercial product at $2.99/mo, $14.99/yr, or $19.99 lifetime. If price is the deciding factor, WinDirStat wins, full stop.
Does WinDirStat find duplicate files?+
No. WinDirStat is a pure visualizer — it shows you what's taking space but doesn't compare files against each other. Diskaroo's Pro tier runs a three-pass byte-exact match (group by size, then a 64 KB partial hash, then a full hash) so a flagged duplicate is identical down to the byte.
Why would I pay for Diskaroo when WinDirStat is free?+
If you're Windows-only and have no duplicate-file pain, you probably shouldn't. The cases where Diskaroo's worth the money: you also use a Mac (one license covers both), you have real duplicate-file pain (WinDirStat won't find them), or you want active development with auto-update and modern UI.
Is WinDirStat still maintained?+
There's a lightly maintained fork at windirstat.net, but the release cadence is intermittent and modern niceties (high-DPI polish, dark mode, Windows 11 native styling) lag well behind. Diskaroo is in active development with regular signed releases on both platforms.
Can I just run WinDirStat on a Mac?+
No. WinDirStat is Windows-only. Mac users typically reach for DaisyDisk, GrandPerspective, or Diskaroo. If you want one tool that runs on both desktops under one license, Diskaroo is the answer; if you don't need the Mac side, WinDirStat is fine.
