The role of the optical disk file system is basically the same as that of the familiar FAT16, FAT32 and other hard disk file systems. The three most common optical disk file systems are:< /p>
ISO-9660: promulgated by the International Organization for Standardization in 1985, it is the only universal optical disc file system, and any type of computer and all burning software provide support for it. Therefore, if you want the burned disc to be read smoothly by all CD-ROM drives, it is best to use ISO-9660 or a compatible file system; other file systems can only be used on CD-R or CD -Reading on RW limits the versatility of discs. ISO-9660 has two standards, Level1 and Level2. Level1 is compatible with DOS, the file name adopts the traditional 8.3 format, and all characters can only be 26 uppercase English letters, 10 Arabic numerals and underscores. Level2 is improved on the basis of Level, allowing the use of long file names, but does not support DOS.
