I have this problem.I downloaded some games with the NTI Iso format and I cant transfer it to my hard drive!A error message keeps popping out saying file size too big when the game is 6GB.While my external hard drive have 100Gb free space.And there is also another format which is NTFS or something i cant really remember.

Overall the error message keep saying these files are too big....so what should I do?
