Beautiful

Color does the explaining.

Every ring is a level deeper; vivid, color-coded families keep related files easy to follow. Drill into any folder with a single, smoothly animated click — and a breadcrumb trail to find your way back.

Fast

A full drive in seconds.

We read the drive's Master File Table directly instead of crawling folder by folder. A full system SSD maps in a few seconds — and exFAT, FAT and removable drives are supported too.

Safe

It won't let you break Windows.

System locations are blocked from deletion, enforced by the app itself. Deletes go to the Recycle Bin by default, with a 5-second countdown so you can always back out.

Protected — can't delete

Heads up — holds app data

Everything else

Built for the moment your SSD says “almost full.”

Size-ranked list

A live side panel ranks everything in the current folder largest-first, color-matched to its ring.

The Holding Pen

Drag files and folders into a staging area, watch the reclaimable total add up, then clear the batch at once.

Recycle or remove

Recoverable by default — send to the Recycle Bin, or delete permanently with a 5-second safety countdown.

Quick actions

Right-click any item to reveal it in Explorer, open it, collect it, or delete it — no detours.

Live updates

The map reflects changes other apps make while it's open — no manual rescan required.

Private by design

It never phones home. Everything runs locally — no network features, no accounts, nothing uploaded.

Trust & privacy

Powerful enough to read your raw disk. Careful enough to never hurt it.

The main app runs without admin rights. Reading the raw disk is isolated into a tiny, auditable helper that runs only during a scan — your one UAC prompt. No telemetry, no uploads, no accounts. What's on your disk stays on your disk.

Beautiful, fast, and safe — all at once.

Questions, answered

Yes. Deletes go to the Recycle Bin by default, so they're recoverable, and there's a 5-second countdown before anything happens. System locations — Windows, Program Files, drive roots, user profiles — are blocked from deletion entirely, enforced by the app itself.
Yes. The fast path uses the NTFS Master File Table, and exFAT, FAT and removable drives are scanned with a standard folder walk. External drives, USB sticks and SD cards all work.
Reading a drive's raw file table requires elevated access. Rather than run the whole app as admin, Space Cowboy isolates that into a tiny, separate helper that runs only during a scan — so you get one UAC prompt per scan and the UI itself never has system-level power.
Completely. Space Cowboy has no network features at all — no telemetry, no uploads, no accounts. Everything stays on your PC.
Windows 10 or 11 (64-bit). The installer is about 6 MB and uses the WebView2 runtime, which installs automatically if it isn't already present.
