File Allocation Table (FAT) is a file system developed for personal computers and was the default filesystem for MS-DOS and Windows 9x operating systems. [citation needed] Originally developed in 1977 for use on floppy disks, it was adapted for use on hard disks and other devices.
Limits. While storage devices usually have their size expressed in powers of 10 (for instance a 1 TB Solid State Drive will contain at least 1,000,000,000,000 (10 12, 1000 4) bytes), filesystem limits are invariably powers of 2, so usually expressed with IEC prefixes. For instance, a 1 TiB limit means 2 40, 1024 4 bytes.
Tux3 – An experimental versioning file system intended as a replacement for ext3. UDF – Packet-based file system for WORM/RW media such as CD-RW and DVD, now supports hard drives and flash memory as well. UFS – Unix File System, used on Solaris and older BSD systems. UFS2 – Unix File System, used on newer BSD systems.
On many older file systems, inodes are stored in one or more fixed-size areas that are set up at file system creation time, so the maximum number of inodes is fixed at file system creation, limiting the maximum number of files the file system can hold. A typical allocation heuristic for inodes in a file system is one inode for every 2K bytes ...
A local file system is a capability of an operating system that services the applications running on the same computer. [ 1 ][ 2 ] A distributed file system is a protocol that provides file access between networked computers. A file system provides a data storage service that allows applications to share mass storage.
exFAT (Extensible File Allocation Table) is a file system introduced by Microsoft in 2006 and optimized for flash memory such as USB flash drives and SD cards. [6] exFAT was proprietary until 28 August 2019, when Microsoft published its specification. [7] Microsoft owns patents on several elements of its design.
The FAT file system is a file system used on MS-DOS and Windows 9x family of operating systems. [3] It continues to be used on mobile devices and embedded systems, and thus is a well-suited file system for data exchange between computers and devices of almost any type and age from 1981 through to the present.
Disk partitioning or disk slicing[1] is the creation of one or more regions on secondary storage, so that each region can be managed separately. [2] These regions are called partitions. It is typically the first step of preparing a newly installed disk after a partitioning scheme is chosen for the new disk before any file system is created.
