I was under the impression that when I moved an aircraft to the hanger that this program zipped that aircraft there by reducing the amount of space the aircraft is taking up on my hard drive. So I moved all but a few aircraft to the hanger. At the time I had 800mb left on my hard drive but now I have 100 mb left on my hard drive so this is actually using more hard drive space. I went to my FS9 and started it up and found that actually I can load all my aircraft? They are still there; nothing has been moved or zipped. So either I miss understand what the program does or I am using it wrong. Help please.
