games don't care if you use NTFS or FAT32, they don't care what your file system is. Given the choice, and ASSUMING you are using XP (or why else would you be here), it seems absolutely silly to have NTFS as an option and not take it. NTFS blows FAT32 out of the water, it is FAR superior. It is a better file system, more secure, if you're into digital video, you can exceed the FAT32 4 gig file size limit, etc etc etc....dump that FAT32 garbage and step up to NTFS!😀
