CleanMyDrive sits in your menu bar. Click its icon, and you see a menu listing all mounted volumes: internal drives, external disks, optical discs, disk images and network shares. Next to each volume’s icon are the volume’s name, a graphical representation of how much space you’re using, and a numerical tally of remaining free space. Use the Eject button to quickly unmount non-internal volumes.
