While working on your Mac you create and download a lot of files, but rarely delete anything. As time goes by you have less and less room for your data. With DaisyDisk get room for your data by removing old junk you unlikely even thought you had.
DaisyDisk gives you a perfect overview of all the disks connected to your Mac, be it Macintosh HD, flash card, Thunderbolt disk or network storage. The list and disk usage gauges are updated in real time, so you always can tell if there's enough space for installing a new game or downloading an HD movie.

Please think about purchasing the app, if you enjoy it.
Seed as long as possible, don't forget to say thanks.
