I am trying to put a full length movie onto my Moment. It is an mpg4 file. Only 1GB. I have a 8GB card. I drag and drop the file into the folder and it starts to download. When it is done it says that the 1GB file is there. When I unhook my phone from the computer it is nowhere to be found. When I hook my phone back up to the computer the "file" is still there but it says it is 0GB. Any help would be great!
