Where did all
your space go?
DriveSize maps every drive in seconds, shows you exactly what's eating it in gorgeous donut charts, and finds the temp junk you can safely bin.
Your disk, at a glance
Click a slice, drill into a folder, tick what you don't need, done. Browsing works while the scan is still running.
Everything TreeSize does.
Prettier.
