About dux
dux, short for Disk Usage eXtended, is a native Mac app that shows where disk space goes, ranks cleanups by what they really free and never moves a file before you review it. The name is a nod to the Unix du command. Scans stay on the Mac. Cleanups go to the Trash or become APFS clones, with Undo, and the few actions that can’t be undone say so before they run.
dux is made by Provaz B.V. in the Netherlands. It is free and complete; Pro and Business add automation and fleet features. See Pricing.
