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 just the folders which are consuming all your free disk space.
It also won’t confuse the picture with all the small stuff, just the ones which will make the most difference if you delete them, ... or if you move them to other storage, like another drive, or into the cloud.
Find out where your disk space went, fast. And then get on with what you were doing.
