File is too big to move
I have a video file which is 4GB and it's currently on my mac hard drive, but when I attempt to move it to my external hard drive which has 184GB free it won't let me and I have an error which says "The item can’t be copied because it is too large for the volume's format". I don't understand why it's too large when I have 184GB free so it should fit onto it fine.
Could someone explain how I could get rid of this message so I can move this file onto my external hard drive.
Many thanks
iMac, Mac OS X (10.7.1)
