I've got two hard drives in my machine, one with Windows and all my installed apps on, and another larger drive with all my music and films on. The larger drive was almost full (less than 1GB left of 120GB) so I moved a folder with some music videos in totalling just over 4GB to the smaller Windows drive. Having gone back into my computer, the larger drive doesn't seem to have any more free space on it, still showing just under 1GB free despite moving the 4+GB folder across (which took 3 or so mins to move). I've checked and checked again and it has gone from where it was so was not copied by mistake, yet it doesn't seem to have free'd up any space. Any ideas?
