Census

Counts your files and shows where they live.

Pick a folder or a whole disk. Census counts the files inside and draws them as rings. Each ring is one level deeper, and a bigger slice holds more files. Click a slice to zoom in, click the middle to zoom out. Disk-space tools tell you how big. Census tells you how many.

Counts a whole startup disk in seconds.
You choose whether hidden files count.
Watches the folder and keeps the count current.
Changes nothing unless you ask.
No accounts, no network, no tracking.

For Mac, macOS 26 or later. Coming to the Mac App Store.
