!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 0.50
by M.Smith
28th June 1992
This is the first read only version of ArcFS 2. A read / write version is
due to be released in October 1992, and should make an appearance at the BBC
Acorn User show. See Acorn Computing press for further details when they are
announced.
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.
Many thanks to David Pilling, author of Spark and SparkPlug, for selling the
full version of ArcFS 1 and for providing me with the information to enable
me to include support for Squashed (PK arc compatible) and Compress formats.
The full version of ArcFS 2 will probably be sold through another publisher
who can sell it at Acorn shows and give it more publicity. The asking price
will ideally be about �20. All offers are welcome, but will need to be made
fairly quickly as I would like to come to an agreement with a company by the
end of July 1992.
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).
The version of ArcFSFiler supplied with this version of ArcFS (v0.50) 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 The Micro User / Archimedes World / Syracuse 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
ArcFS 2 will load files in half the time (on average) that ArcFS 1 took.
The following is a guide to performance with an ARM 2:
Loading from floppies takes about 20% longer if the files are archived
(files compressed to below 20% can take less time to load from an
archive).
Loading from a hard disk takes about 10 times as long if files are
archived (remember that hard disk loading times are usually of the
order of a few tenths of a second - ArcFS 2 will take a few seconds
to load files from a hard disk.)
Performance with an ARM 3:
Loading from floppies should take about the same length of time whether
or not files are archived.
Loading from a hard disk should take about 5 times as long.
N.B. Since I don't have an ARM 3, the ARM 3 times are based on the little
information I have been given by other people.
ArcFS 2 will read ArcFS archives, Spark archives and most archives produced
on a P.C. by P.K. PAK or SEA arc.
