DiskWatch — see where your disk space went.

A small menu bar app for Mac. Live free space, a desktop widget, a full report of what is taking room, and a safe way to clear it.

Live reading

🟢 142 GB in the menu bar, refreshed every minute. Yellow under 15%, red under 5%.

Full report

Biggest folders and files, what kind of thing each is, and how long since it was touched.

Safe clean-up

Caches pre-ticked, everything goes to the Trash — never deleted outright.

Private

Your files never leave the Mac. Only your licence is checked online.

Get Started

Help

Installing

Sign in → Download → open DiskWatch-…pkg. The first time macOS refuses it (no Apple signature yet): System Settings → Privacy & Security → Open Anyway, or right-click the .pkg → Open → Open.

Activating

After installing, DiskWatch asks you to Activate: sign in with the same account. If you were given a DW1-… key, enter it on Create account or in Account → Licence.

Using it on another Mac

Your licence allows a number of Macs. Account → Macs lists them; remove one to free its place.

“DiskWatch is not activated”

The licence is re-checked every 15 minutes. Offline it keeps working for a day. If the licence was revoked or ran out, enter a new key in Account.

Permissions

For a complete scan add DiskWatch under System Settings → Privacy & Security → Full Disk Access. DiskWatch's Settings → Permissions has a button for it.

Uninstalling

Quit DiskWatch, drag /Applications/DiskWatch.app to the Trash, and remove the two com.niyanta.diskwatch files in ~/Library/LaunchAgents.
