So I was going to partition my drive but I thought it froze. I clicked the X and it said blah blah unsaved stuff so I was like "okay it'll just stop everything and not do it." Wrong. Now instead of having 100GB of used space I have 200GB. In my about this mac it says that that space is filled with "other". Any help as to what I can do to get rid of this extra space that hold no content(to my knowledge)?
