Windows Update leftovers
Installed updates Windows keeps "just in case". Often the biggest single win.
Your C: drive is full.
Let's fix that.
Roomy shows you what's eating your space, in plain English, and clears the safe stuff in one click. A free storage cleaner for Windows that doesn't try to sell you anything.

You just freed 0 GB. That's the whole app: no account, no upsell.
Knows where the junk hides.
On a typical PC that's 10–40 GB you didn't know you could get back.
App caches
Discord, VS Code, Slack, Teams, Steam, npm, pip, Yarn, NuGet. They rebuild what they need.
Browser cache
Chrome, Edge, Brave, Vivaldi, Firefox and Opera. You stay logged in everywhere.
GPU shader cache
NVIDIA, AMD, Intel and DirectX caches that quietly grow into gigabytes.
Games you forgot about
Reads your Steam library and finds the 70 GB game you last opened in March. Uninstalls through Steam.
Old installers & downloads
That 300 MB setup.exe you ran once. Always unticked, always your call.
The space map
Not sure what "Other" is? Click down through any drive folder by folder, and see the single biggest files on your PC in one list.
Boring on purpose.
Most "PC cleaners" are scary for a reason. Roomy only looks in known junk folders, and explains everything before it touches anything.
- Your files are off-limits. Documents, Desktop, Pictures, Videos and Music are hard-blocked in the code.
- Nothing happens without a click. Scanning only reads. "Your call" items start unticked and ask again.
- In-use files get skipped. If an app is using something, Roomy leaves it alone.
- Uses Windows and Steam where it should. Old Windows backups and games go through their own uninstallers.
- Fully offline. No uploads, no tracking, no account. Every line is on GitHub.
Brag a little.
When you're done, Roomy makes a before-and-after card you can paste straight into Discord or the group chat.
Questions
Is it actually free?
Yes. No trial, no "Pro", no ads. It's open source under the MIT license.
Will it delete my files?
No. Roomy only looks in known cache and temp locations, and your personal folders are blocked in the code. Downloads are only ever suggested, unticked, and you confirm before anything is removed.
Why does it ask to restart as admin?
Windows locks its own update leftovers. Roomy works fine without admin; it just can't clean those until you allow it.
Does it send anything anywhere?
No. Roomy doesn't connect to the internet.
Mac or Linux?
Not right now. Roomy is made for Windows 10 and 11.
