  BeOS - Wikipedia, the free encyclopedia
BeOS PE could be started from within Microsoft Windows or Linux, and was intended to nurture consumer interest in its product and give developers something they could tinker in.
Unfortunately, BeOS PE and BeIA proved to be too little too late, and in 2001 Be's intellectual property was sold to Palm, Inc. BeOS R5 is considered the last official version, but BeOS R5.1 "Dano", which was under development before Be's sale to Palm, was leaked to the public shortly after the company's demise.
The plain BeOS R5 GUI is commonly cloned, either as the main UI, such as in TriangleOS, or as a theme, such as for SkyOS or GNOME.

 Be File System - Wikipedia, the free encyclopedia
The Be File System (BFS, occasionally misnamed as BeFS) is the native file system for the BeOS operating system.
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.
Like its predecessor, OFS (Old Be File System, was also called BFS when current), it includes support for extended file attributes (metadata) with indexing and querying characteristics to provide functionality similar to that of a relational database.

 The New BFS (Brendan File System) - OSNews.com
Current file systems are horribly out-of-touch with the realities of what users need to effectively find, organize, and modify their vast quantities of files.
The Be file system basically nailed this with extendable attributes and live queries, and the BFS embraces this system whole-heartedly.
But where the Be file system made these queries persist at the application level, the BFS lets users and programmers create and extend groups by adding a search pattern to their metadata.

 BeBits Wiki - BeOSFileSystemAPI
Some file systems have it as a copy of the actual disk sector with the info about the file, but then that forces them to use one whole sector for every file's info, though it does make it easy to write the updates back to the disk.
Anyway, it distinguishes between different mounted file systems, and is used to identify the particular instance of a file system for calls like Notify, which along with a vnode_id tell the OS that a particular file on a particular file system has changed.
Files that change the indices after open_query get sent as notification messages (if it would change the value reported by read_query, even if the caller hasn't gotten that far in read_query), and maybe also show up in read_query if the underlying iteration of read_query hasn't reached that file yet.

 Tracker's Identify Command   (Site not responding. Last check: 2007-10-22)
Most files on the Internet are compressed into archives; the archive itself has a MIME type from the Internet transmission, but the files inside it may not -- few other operating systems use attributes on files as extensively as the BeOS.
Sometimes you want the BeOS to do it right away so, as you've probably figured out by now, the Identify command is a way to force the Tracker to try to figure out the file's (or files') type immediately.
In the BeOS Preview Release 1 and 2, the Tracker's window needed to be closed and then re-opened before the Tracker would show the effects of the Identify command.

 CS 5541   (Site not responding. Last check: 2007-10-22)
The problem is that BeOS crashes when you write large files in the BeOS file system.
It does seem OK with writing files in in a mounted Windows file system, however.
The workaround for right now is to mount the windows file system (right click on the desktop, go to "mount" and mount the windows file system), and do any writing to files there.

 BeOS File System   (Site not responding. Last check: 2007-10-22)
The Be File System (BFS, BeFS) is the native file system for the BeOS operating system.
BFS was developed by Dominic Giampalo and Cyril Meurillon in 1996 over a 10 month period to provide BeOS with a modern 64-bit capable journaling file system.
Its design process, API, and internal workings were, for the most part, documented in the book "Practical File System Design", ISBN 1558604979.

 BeOS - a Whatis.com definition   (Site not responding. Last check: 2007-10-22)
BeOS is a personal computer operating system that its makers describe as designed for the multimedia applications of the future.
BeOS can run on multiple microprocessors at the same time (using symmetric multiprocessing) and is able to coordinate work threads across the processors.
BeOS comes with a desktop user interface that improves in some ways on both Windows and the Mac and a built-in Web browser, audio, MIDI, and its own 3D interface as well as support for OpenGL.

File systems may not be the center of many water cooler conversations, but Microsoft's next-generation plans have been the subject of much rumor mongering and guesswork amongst Windows enthusiasts.
Currently, the NT File System (NTFS) rules the roost, providing the storage foundation to NT, Windows 2000 and XP (with slight changes, here and there).
File systems are perhaps the most antiquated feature of modern OSes.

 Operating Systems and File Systems BeOS
The Be operating system was intended to be an alternative to the heavy weight (literally) operating systems used by most people.
While this operating system enjoys only a very small percentage of the overall operating system market, it is an important option for audio and video hobbyists and power users.
This new operating systems primary file system is its very own, unique, BeOS File System, which is abbreviated as BFS or befs.

 MacOSX Week: Tales of a BeOS Refugee - OSNews.com
The story of how a BeOS refugee (and not just everyone, but the author of the 'BeOS Bible' book) lost faith in the future of computing, resigned himself to Windows but found himself bored silly, tore out half his hair at the helm of a Linux box, then rediscovered the joy of computing in MacOSX.
To rub salt into wounds, Mac OS opponents have historically loved complaining that the Mac was saddled with ill-conceived evolutionary sink-holes like the single-button mouse and the coup de grace, a total absence of anything resembling a command line.
BeOS really was the promised land of operating systems, as far as I was concerned, and it was only a matter of time before the rest of the world saw the light.

 Amazon.co.uk: Practical File System Design with the Be File System: Books   (Site not responding. Last check: 2007-10-22)
Built from scratch as a modern 64 bit, journaled file system, BFS is the primary file system for the Be Operating System (BeOS), which was designed for high performance multimedia applications.
This work provides an in-depth look at the BeOS from the vantage point of the operating sustem's file system design and implementation issues in general, and looks at how those issues were handled in the development of the BeOS.
I especially found the performance comparisons of popular file systems useful, giving the reader the ability to analyze the trade-offs of the differing implementations, and how those design decisions are based on the requirements of the file-system.

 HubLog: BeOS file system with metadata for OS X   (Site not responding. Last check: 2007-10-22)
Any file or file type on a BFS volume can have arrays of metadata associated with it, in the form of "attributes." There is no limit to the amount, size, or type of attributes, and attributes can be displayed and edited, sifted, sorted, and queried for directly in the Tracker (Be's equivalent of the Finder).
By default, BeOS ships with reasonable sets of attributes for common file types, but users are allowed to extend and customize these, and to create entirely new file types with entirely new arrays of attributes.
In other words, the Be File System doubles as a database.

 More Be for me and hopefully you, too
A journaled file system means that BeOS keeps track of all file system changes to the journal before they are written to the disk, and it does so in real time - as the system runs.
And multithreading the file system ensures that it provides the best possible performance for all file system services, including journaling, without reducing the processing capability of the PC any more than absolutely necessary.
The file system is also built to be "database-like," which allows arbitrary attributes to be appended to files and used in searches.

 Scripting with the Be File System
For those of you just joining us, files on a BFS volume can store arbitrary amounts and kinds of associated meta-data, in the form of "attributes." Typically, attributes are associated with specific filetypes.
So not only is it possible to run queries on BeOS that just aren't possible with other operating systems, but attribute queries do not force the operating system to iterate over every file in the search path.
This is useful if your script is creating files which aren't immediately being given filetypes by the Tracker, or in case you want to override BeOS' default filetype identification routines.

 BeOS File System (BFS)
The BeOS operating system is designed to use its own file system, called (unsurprisingly) the BeOS File System, abbreviated BFS or sometimes befs.
BFS is based strongly on the fundamental design concepts of the UNIX file systems, so those experienced with UNIX will find much that is familiar in BFS.
These are in addition to most of the benefits associated with UNIX file systems, though there are of course tradeoffs; it wouldn't be accurate to say that BFS was "better than" UNIX file systems, for example.

 The MusicWeaver and other stuff for BeOS
matt was available first for BeOS, because that's where I developed it, but it's straightforward posix code and also runs on Linux etc. I've packaged the source with a fairly general Makefile.
This package allows you to mount your Psion Series 5 (5mx or Revo) as a BeOS file system, and access the Psion from the Tracker.
The source — except for one slightly patched file and the Makefile — is therefore not included in the package, as it is readily available from the author's own site.

NFS, or Network File System, is the standard mechanism for Unix-based computers to share files with one another.
However, NFS is a general-purpose file system intended to operate identically on a number of different operating systems.
Because CIFS is designed to run on Microsoft operating systems, however, it does not support the unique features of the Be File System (BFS), such as attributes, MIME-based typing, indexing, querying, and so on.

 The BeOS Tip Server : Home
The BeOS file system maintains a number of indices of the content of your most-used attributes in order to make queries lightning fast.
Note, however, that this merely re-establishes the existence of the index -- it does not automatically add all applicaple data on your system to the index.
The act of copying the files to a new location causes the filesystem to index the attributes being written.

 Good News for BeOS Aficionados
Yesterday, the file system team from the OpenBeOS Project (one of several current efforts to bring the BeOS back to life as open-source software) announced that the fruit of their efforts, OpenBFS, has reached beta stage and is ready for testing.
However, this file system announcement might be enough to evoke in me a guarded optimism.
With BeOS, applications didn't always take advantage of the BFS, and loss of attributes when moving from BFS to other file systems tended to pose problems.
