OmniDiskSweeper useage
Hi
I'm looking to clear space on my hard drive. After sweeping what I take to be the whole computer with OmniDiskSweeper (1.9 v28 r201186) it only seems to find 220.3GB of the reported 410GB used, see attached screen shot. I can't locate any other drive or hidden directory. Am I missing something? How do I get to see the other 190GB?
I'm using OS X 10.9.5.
Many thanks.
iMac, OS X Mavericks (10.9.5)
