Ok this is my situation. Sometime in the last 48 hours, I lost 45-50 gbs and I dont know where. I don't know if there is a temp file in OS X I can delete or clear. I attached a screenshot of a program Whatsize to show what Im talking about. If you look at the top it says theres 57 gbs of data on the disk. Yet the drive claims theres 511 mbs free on a drive with a 111 gb capacity. Any help would be appreciated since there is a lot of things I can't do because its claiming there isn't enough free sapce on the disk. Thanks in advance.
