While working on your Mac you create and download lots of files, but rarely delete anything. At some point you find that your startup disk is full. What to do?

Well, a larger disk will cost you a few hundred dollars. Yearly fee for a cloud storage is about the same. Or simply get DaisyDisk at a fraction of the price and make plenty of space by removing old junk.

On all your disks

DaisyDisk also gives you a great overview of all connected disks, be it Macintosh HD, Thunderbolt disk, flash, network storage, you name it.

All displayed data are updated in real time, so you can always tell if there's enough space to install a new game or download an HD movie.

How it Works

It's easy. Just scan a disk and see all of your files and folders as a visual interactive map. Find an unusually large file. Preview its content, and delete if you don't need it anymore.


Only you decide what to delete. System files are protected.


Scanning modern disks takes only a few seconds---a far cry from any rival.


DaisyDisk remains the tool of choice for IT professionals, photographers, film makers and artists worldwide.

Cost Effective

Use your existing storage instead of buying more of it.
