Which of the following file system types is used for optical media?

FAT32 is a file system used on hard drives, USB flash drives, and memory cards, supporting volumes up to 2TB with individual file sizes up to 4GB - it is not used for optical media.

FAT (FAT16) is an older file system for hard drives and removable storage with a 2GB volume size limit - it is not the file system used on optical discs.

CDFS (Compact Disc File System), also known as ISO 9660, is the file system standard specifically designed for optical media including CDs and DVDs. It defines the logical format for data stored on optical discs and is recognized by all major operating systems. This file system is optimized for the read-only, sequential-access nature of optical media, unlike FAT or NTFS which are designed for read-write magnetic or flash storage.

NTFS is the primary Windows file system for hard drives and SSDs, offering advanced features like permissions, journaling, and encryption - it is not used for standard optical media.
