It's so frustrating when your disk is full and the operating system expects YOU to know where it all went!

Disk Space Finder will quickly analyse your disk, (or a selected part of it), and show you all the folders which are hogging your space.

It won't confuse the picture with all the small stuff, just the ones which will make the most difference if you delete them, ... or move them to other storage, like another drive, or into the cloud.

Just click that slice of the pie, or the legend, to open the folder in the Finder.

Find out where your disk space went, fast. And then get on with what you were doing.
