=== Disk file systems ===

A ''disk file system'' takes advantages of the ability of disk storage media to randomly address data in a short amount of time. Additional considerations include the speed of accessing data following that initially requested and the anticipation that the following data may also be requested. This permits multiple users (or processes) access to various data on the disk without regard to the sequential location of the data. Examples include [[File Allocation Table|FAT]] ([[FAT12]], [[FAT16]], [[FAT32]]), [[exFAT]], [[NTFS]], [[ReFS]], [[Hierarchical File System (Apple)|HFS]] and [[HFS Plus|HFS+]], [[High Performance File System|HPFS]], [[Apple File System|APFS]], [[Unix File System|UFS]], [[ext2]], [[ext3]], [[ext4]], [[XFS]], [[btrfs]], [[Files-11]], [[Veritas File System]], [[VMFS]], [[ZFS]], [[ReiserFS]], [[Novell Storage Services|NSS]] and ScoutFS. Some disk file systems are [[journaling file system]]s or [[versioning file system]]s.

==== Optical discs ====

[[ISO 9660]] and [[Universal Disk Format]] (UDF) are two common formats that target [[Compact Disc]]s, [[DVD]]s and [[Blu-ray]] [[optical disc|discs]]. [[Mount Rainier (packet writing)|Mount Rainier]] is an extension to UDF supported since 2.6 series of the Linux kernel and since Windows Vista that facilitates rewriting to DVDs.
