If you need to access some files from DOS mode or Windows 9X, you have to use FAT32 file system. FAT32 is an older file system compared to NTFS, but it is simple and readable from a great number of operating systems, and also supported by a wide range of system utilities. FAT32 can well work on DOS v7 and higher Windows 98, ME, 2000, etc.
