I have 1TB of storage. Even if I delete all the movies that are listed under "All My Files" it doesn't seem to be that much. Where can I see what is taking up how much space?

Oh, yes. This will eat up a lot of storage memory. However, it is a "reserve" usage and will be overwritten if need be. I hate it, because it makes it look like you have used up all your memory.
