Broom is a lightweight, easy-to-use disk cleaning utility for your Mac. It has two life-saving features: Broom alerts you when your disk space is running low and helps you to quickly pick and choose what needs to be cleaned up.
Once installed, Broom sits quietly in your menubar. One click on the Broom icon shows you how much space you've got left on your hard drive. If you're running low, Broom will let you know and help you to zero in on the biggest offenders immediately.
