Good evening all, I have a 50gb iCloud account, of which I use about 30gb for documents, photos, etc. I've noticed my rMBP hard drive slowly dwindling and in trying to delete files came across the "Mobile Documents" folder in my user library folder. This seems like a complete duplicate of my iCloud Drive. I was always under the impression that files kept on iCloud didn't take up any space on the local drive. Why is that folder 30gb in size? I keep photos and movies in iCloud, so they don't take up space on my laptop. Can someone clear up what's going on? Thanks!
