What you get with PocoDisk
- 01
Sunburst Visualization
The iconic radial chart of disk usage — folders sized proportionally, the offenders impossible to miss.
- 02
Collector Workflow
Drag files into a basket as you browse. Review, then delete the whole basket at once.
- 03
Quick Look Built-in
Hit Spacebar on any file to preview it inline — never delete the wrong thing again.
- 04
APFS Purgeable Space
Surfaces system-hidden purgeable storage so you finally see where your disk really went.
- 05
Procedural App Icon
The PocoDisk icon is generated at build time entirely in Swift — no PNG assets to maintain.
- 06

Get Started
Up and running in 5 steps
- 01
Clone the repo
Grab the source from GitHub.
git clone https://github.com/joeydash/PocoDisk.git - 02
Build the app
Run the build script — produces PocoDisk.app in the project root.
cd PocoDisk && ./build.sh - 03
Open it
Launch the freshly built app.
open PocoDisk.app - 04
Grant full disk access
macOS will prompt for Full Disk Access so PocoDisk can scan every folder. Approve once in System Settings.
- 05
Pick a volume and scan
Choose the drive to analyze. The sunburst paints as the scan progresses — start reclaiming space immediately.
How It Works
Three steps to a cleaner Mac
- 01
Scan your drive
Pick a volume — internal disk, external SSD, network share — and PocoDisk walks the filesystem to map every byte.
- 02
See the sunburst
The radial chart paints folder sizes proportionally. The huge wedges are exactly what you need to deal with first.
- 03
Collect & reclaim
Drag bloat into the collector basket, preview with Quick Look, then move it all to Trash in a single click.
