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.

File contents
!Help file for ArcFS version 0.72c (Beta) by M.Smith 16th Feb 1995 The current full version is v2.52 - Details of how to get it are in the info box. Full information on ArcFS is available as part of the 'ArcFSExtra' package, along with technical documentation and utilities. 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 bases (&437C0 and &48A00) and Filetype (&3FB). ArcFS allows the loading and opening of 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 course, 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. *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. *New to v0.65 / v2.23* Memory management has now been separated out into another module. Dynamic area memory management included for RISC OS 3.5 in v2.24 *New to v0.70 / v2.50* Improved RISC OS 3.5 memory management + Bug fixes. The read only version is now smaller - some resources are stored compressed within the application & the ArcFS module is compressed with Acorn's DDE Squeeze utility. This is the release final version that does not need MessageTrans - Future releases will be fully internationalised and on RISC OS 2 machines will need to load it from !System. ***************************************************************************** All comments and suggestions for future improvement are welcome but please note that I cannot reply to letters without A STAMPED, ADDRESSED ENVELOPE.
