i have used wii backup manager to transfer 4 games iso's to a wd external hard drive formatted in ntfs, when the games were sent over it happened very quickly not like sending a file in windows which takes several minutes and if i check the drive after the games are transferred they all report as 4,589,824 each making a total of over 17gb but if i right click the drive and go to properties the drive only shows as using 1.09gb space, am i missing something here or is backup manager doing something to the iso.
