I'm no newbie when it comes to computers, but I was wondering why when I try to move a 4.37GB Wii game ISO from my C drive to my external it says I don't have enough space. The external has nearly 140GB free space, defragged it, and ran a disc cleanup amongst other things. I'm currently compressing the file, but it's taking a while. Any ideas? EDIT: I should add I just moved 9GB of avi files to the very same drive, from the same drive. I'm thinking the ISO's size is too big? EDIT^2:I think I answered my own question. The external drive is formated in FAT32, which has a max file size of around 2GB. I'm in the middle of converting it to NTFS Apparently Windows XP has such an application built right into it, nifty.
