5 unusual facts about File System


Collation

Collation is a fundamental element of most office filing systems, library catalogs and reference books.

Colony Framework

In practice this implies that even core HTTP server components, such as filesystem access and socket interfaces, are provided as modules and can be hotswapped.

Filing system

File system, a method of storing and organizing computer files and their data

PC booter

These disks contained no filesystem; instead, the custom loader would read the tracks directly.

Write-ahead logging

File systems typically use a variant of WAL for at least file system metadata called journaling.


Data Access Language

However, like any server software on the "classic" Mac OS, Butler was seriously hampered by the Mac's single-user file system and limited multitasking and could never really deliver the sort of performance the same server would have on Windows NT or Unix.

Data scrubbing

Btrfs — as a still experimental copy-on-write (CoW) file system for Linux — provides fault isolation, corruption detection and correction, and file system scrubbing.

Design rule for Camera File system

Design rule for Camera File system (DCF) is a JEITA specification (number CP-3461) which defines a file system for digital cameras, including the directory structure, file naming method, character set, file format, and metadata format.

OpenVMS

OpenVMS has a very feature-rich file system, with support for stream and record-oriented IO, ACLs, and file versioning.

Parallel Virtual File System

The object-based design has become typical of many distributed file systems including Lustre, Panasas, and pNFS.

Speculative execution

This technique is employed in a variety of areas, including branch prediction in pipelined processors, prefetching memory and files, and optimistic concurrency control in database systems.

System Monitor

The categories of information that you can monitor depend on which networking services are installed on your system, but they always include File System, Kernel, and Memory Manager.

Write once read many

However, these disks often use a file system based on ISO 9660 that permits additional files, and even revised versions of a file by the same name, to be recorded in a different region of the disk.

YAFFS

Yaffs (Yet Another Flash File System) was designed and written by Charles Manning, of Whitecliffs, New Zealand, for the company Aleph One.

ADFS

Advanced Disc Filing System, a file system implemented in Acorn and RISC OS computers

AV receiver

USB (usually involves special computer circuitry to read video formats from a file system)

Btrfs

All the file system's trees—including the chunk tree itself—are stored in chunks, creating a potential chicken-and-egg problem when mounting the file system.

Condusiv Technologies

The company was formerly known as Diskeeper Corporation, a name derived from its flagship product, Diskeeper, a file-system defragmentation software package for Microsoft Windows and OpenVMS.

FFS2

FFS2, Unix File System, Berkeley Fast File System, the BSD Fast File System or FFS

Final Fantasy Chronicles

Final Fantasy IV features computer animated cutscene sequences, while Chrono Trigger features anime-style sequences designed by Akira Toriyama that "help further tell the story of Chrono Trigger." Final Fantasy IV was given gameplay features such as a two-player mode, a "Sprint Feature" to "enhance and quicken gameplay", and the "Memo File" system to "reduce saving time." Chrono Trigger, instead of added gameplay features, has an "Extras Mode".

Fusion File System

It uses a layered device driver architecture, using a simple binding model, to allow operating system agnostic or independent portability; meaning that the file system is compatible with most operating systems and is thus not bound to any one RTOS.

Hierarchical File System

HFS was introduced by Apple in September 1985, specifically to support Apple's first hard disk drive for the Macintosh, replacing the Macintosh File System (MFS), the original file system which had been introduced over a year and a half earlier with the first Macintosh computer.

INCITE

The Cray XT system utilizes over 45,000 of the latest quad-core Opteron processors from AMD and features 362 terabytes of memory and a 10-petabyte file system.

Persistent browser-based game

Games relying on client-side technology are rarer due to the security aspects that must be dealt with when reading and writing from a user's local file system - the web browser doesn't want web pages to be able to destroy the user's computer, and the game designer doesn't want the game files stored in an easily-accessed place where the user can edit them.

Proc

proc filesystem, a special file system (typically mounted to /proc) in Unix-like operating systems for accessing process information

Shadow paging

One solution, employed by the WAFL file system (Write Anywhere File Layout) is to be lazy about making pages durable (i.e. write-behind caching).

STOIC

STOIC came with its own primitive but effective file system, and could be booted up with little preliminary work on any 8080-based microprocessor with 24K of memory and a Teletype machine.

Sun Open Storage

Core features provided by Solaris include the operating environment, the ZFS file-system, an analytics tool based on Dtrace, the Network File System (NFS) and CIFS protocol interfaces and other core features.

UBIFS

The file system is developed by Nokia engineers with help of the University of Szeged, Hungary.

Unix File System

Marshall Kirk McKusick, then a Berkeley graduate student, optimized the BSD 4.2's FFS (Fast File System) by inventing cylinder groups, which break the disk up into smaller chunks, with each group having its own inodes and data blocks.
