Did you empty your trash?Hey. I deleted some movies from my air, and suddenly my other storage increased by 4 gb or something. Why?
You can just leave it if you want and OS X will shrink that space if the storage is needed. Or if you want to delete it now just turn Time Machine off then back on and it will get zeroed out.
I have tried that 10 times it doesn't delete anything in the .mobilebackups.TRASH.
It's annoying I have just lost 14 gb of storage.
