!ArcFS/!Help

This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.

Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

!Help file for ArcFS version 0.61
by M.Smith
11th October 1993

ArcFS v2.20 will be sold under the Software 42 label by Vertical Twist. Full
pricing details are still to be finalised.  

Full information on ArcFS is available as part of the 'ArcFSExtra' package.
A utility to convert Spark format archives to new format archives, the
!ArcFSInfo application for displaying full infomation on ArcFS objects and
archives (including both full and compressed sizes) and a utility for
ensuring the presence of ArcFS 2 (like RMEnsure, but will ensure that ArcFS
2, read only or read / write, and not ArcFS 1 is present.) are also included.

This version of ArcFS is not P.D., but may be distributed subject to the
conditions in the 'Licence' file.

ArcFS has filing system number 56. My thanks to Acorn for the allocation of
this filing system number and for the allocation of the SWI chunk base
(&437C0) and Filetype (&3FB).

The version of ArcFSFiler supplied with this version of ArcFS should work
with all versions of Oak's SCSI and Ian Copestake Software's IDE Hard drive
software.

Please note that I can no longer offer a registration service. If anyone
finds ArcFS very useful then please buy the full read / write version or
send a donation to one of the addresses below. Future improvements will be
sent to Acorn Computing / Archimedes World / Acorn User / Illusions Disk
Magazine / The ARM Club for distribution. Please also note that I will no
longer be sending out improvements automatically to P.D. libraries. Again,
upgrades will be available through the above magazines.

ArcFS allows the loading and opening of (compressed) files in archives  as
easily as files on ADFS or RamFS. It has its own ArcFS filer  which displays
the root directory in a filer window of any archive  which is double
clicked. From then on files and applications may be  loaded as normal by
double clicking them. Directories may be displayed  also by double clicking
them. ArcFS can, of cause, also be used from  the command line. Facilities
for loading encrypted files are included, via a preferences window which can
be obtained by clicking on the ArcFS icon. An option to display the
hourglass whilst ArcFS is working is also provided

The performance of ArcFS depends on many variables such as the machine you
are using and the media (hard disc, floppy, network etc.). Loading from
floppies should be as fast or faster than loading the same material,
uncompressed. Loading from hard disc will usually be slightly slower when
using compressed data.

*New to v0.55*

The major new feature is that archives now appear just like ordinary
directories, when used with Risc OS 3, i.e. ArcFS is an image filing system
to use the technical term. Use with Risc OS 2 is just the same as previous
versions, but note that Risc OS 2 support may be removed from future
versions.

Also, if any file of a type other than &DDC is dragged to the ArcFS icon, it
will be checked to see if it is an archive (any of the above types). If it
is then it will be re-typed as &DDC and the top level directory will be
displayed.

Risc OS 3 desktop boot files are now supported - a line loading ArcFS will
be included if a boot file is created when it is running.

The icon now always appears in the correct place on the Risc OS 3 icon bar,
i.e. to the right of all other filing system icons, but to the left of any
!Printers icons. (Priority = &0FFFFFFF)

Plus bug fixes (mainly 'ArcFS CSD is unset' bug).

*New to v0.56 / v2.10*

Support is now included for appliaction archives in the form of a patch
module which makes application archives appear to the Filer like application
directories.

*New to v0.60 / v2.20*

Now *MUCH* Faster. Support for a new archive filetype (&3FB) so ArcFS
archive aren't loaded by SparkFS. Full version also now puts a second copy
of file catalogue information immediately before the file data to make
recovery of files from corrupt archives easier.
