A gigabyte (derived from the SI prefix giga-) is a unit of information or computer storage equal to one billion (short scale) bytes or 230 bytes (1024 mebibytes)[1].

Most modern file systems have methods of administering permissions or access rights to specific users and groups of users. ... Filesystem-level encryption, is a form of disk encryption where individual files or directories are encrypted by the file system, in contrast to full disk encryption where the entire partition or disk, where the file system resides, is encrypted. ...

BFS was developed by Dominic Giampaolo and Cyril Meurillon over a ten month period, starting in September 1996^[2], to provide BeOS with a modern 64-bit capable journaling file system^[3]. It is case sensitive and capable of being used on floppy, hard disks and read-only media such as CD-ROMs, although its use on small removable media is not advised, as the file system headers consume from 600KB to 2MB, rendering floppy disks virtually useless. Dominic B. Giampaolo is a software developer who currently works for Apple Computer, where he is part of the Mac OS X file system and Spotlight groups. ... Year 1996 (MCMXCVI) was a leap year starting on Monday (link will display full 1996 Gregorian calendar). ... BeOS is an operating system for personal computers which began development by Be Inc. ... In computing, a 64-bit component is one in which data are processed or stored in 64-bit units (words). ... A journaling (or journalling) file system is a file system that logs changes to a journal (usually a circular log in a specially-allocated area) before actually writing them to the main file system. ... Text sometimes exhibits case sensitivity, that is, words can differ in meaning based on the differing use of uppercase and lowercase letters. ... A floppy disk is a data storage device that comprises a circular piece of thin, flexible (hence floppy) magnetic storage medium encased in a square or rectangular plastic wallet. ... Typical hard drives of the mid-1990s. ... The CD-ROM (an abbreviation for Compact Disc Read-Only Memory (ROM)) is a non-volatile optical data storage medium using the same physical format as audio compact discs, readable by a computer with a CD-ROM drive. ...

Like its predecessor, OFS (written by Benoit Schillings, Old Be File System, was also called BFS when current^[4]), it includes support for extended file attributes (metadata) with indexing and querying characteristics to provide functionality similar to that of a relational database. Benoit Schillings, currently the chief technology officer at TrollTech[1], is famous for being one of the lead developers of the BeOS operating system and is a noted amateur astronomer. ... Metadata is data about data. ... A relational database is a database that conforms to the relational model, and refers to a databases data and schema (the databases structure of how that data is arranged). ...

Whilst intended as a 64-bit capable file system the size of some on-disk structures mean that practical size limit is approximately 2 exabytes. Similarly the extent based file allocation reduces the maximum practical file size to approximately 260 gigabytes at best and as little as a few blocks in a pathological worst case depending on the degree of fragmentation. In computing, file system fragmentation, sometimes called file system aging, is the inability of a file system to lay out related data sequentially (contiguously), an inherent phenomenon in storage-backed file systems that allow in-place modification of their contents. ...

Its design process, application programming interface, and internal workings are, for the most part, documented in the book Practical File System Design with the Be File System. An application programming interface (API) is a source code interface that a computer system or program library provides to support requests for services to be made of it by a Length. ...

Implementations

In early 1999, Makoto Kato developed a Be File System driver for Linux, however the driver never reached a complete stable state, so in 2001 Will Dyson developed his own version of the Linux BFS driver^[5]. Linux (IPA pronunciation: ) is a Unix-like computer operating system. ...

As part of the OpenBeOS attempt to recreate the BeOS operating system, in 2002 Axel Dörfler and a few other developers created and released a reimplemented BFS called OpenBFS^[6]. In January 2004, Robert Szeleney announced that he had developed a fork of this OpenBFS file system for use in his SkyOS operating system^[7]. Haiku, formerly known as OpenBeOS, is an open source project dedicated to the re-creation and continuation of the Be Operating System on x86 and PowerPC based computers. ... SkyOS is an operating system developed by Robert Szeleney. ...
