Underbrush help

Underbrush shows you what's filling your drive, says what each thing is, and clears the parts that are safe to clear. Press Scan, look at the list, and press Free up when you're happy.

It sorts everything it finds into piles: Safe to clear, Your call, Cloud and Leave it. Only the first one is ticked for you. Nothing is deleted until you see the list and the total and press Clear.

Start here

• Getting started: scan your drive and free up space for the first time.
• The piles and the safety rules: what Underbrush will and won't touch.
• Dashboard: where your space went, at a glance.
