Menu-bar disk monitor for macOS

Know exactly what's
filling your disk.
Reclaim it in seconds.

DiskBar sits in your menu bar, watches every volume in real time, and surfaces the largest files the moment you're running low.

What it does

Built for the moment the disk fills up.

No dashboards to open, no scans to schedule. DiskBar keeps watch and steps in exactly when you need it.

// live

Real-time monitoring

Every mounted volume, tracked continuously. A glance at the menu bar tells you how much room is left.

// scan

Largest-file finder

Sort any volume by what's actually taking the space, from multi-gigabyte caches down to forgotten downloads.

// act

One-click cleanup

Reveal a file in Finder or move it to the Trash without leaving the dropdown. See space return immediately.

How it works

Three steps, then it stays out of your way.

Pin it to the menu bar

Launch once and DiskBar takes its place beside the clock. No window, no dock icon in the way.

Watch the usage bar

The volume meter fills as your disk does. When free space runs thin, the readout turns amber.

Clear the big offenders

Open the scanner, spot the largest files, and remove what you don't need in a couple of clicks.
