i am trying to backup a wii game. The file size is 4.37 gigs but nero says there is not enough space. I am really confused I just backed up another game perfectly and its working fine. I went to try to backup the same game I already successfully backed up and it says it is also too big but i just did it yesterday. The message says its too big by 476 kb. Ne suggestions or solutions to why this wont backup what I already did successfully?
