Documents/OpenArcs
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
ArcFS 0.50/2.00 Documentation ----------------------------- Simultaneously open archives ---------------------------- This version of ArcFS supports an unlimited number open at any one time, although the ArcFSFiler can only display up to the first 44 in the Archive menu. Each archive must be refered to by a unique name (usually, but not necessarily, the leaf name of the archive). This is name is provided when the archive is opened using *OpenArchive and can then be included in the special field to refer to that specific archive. The ArcFS Filer uses the leaf name of the archive as its name. If you try to open an archive with the same name as one that is already open with *OpenArchive then an error will be returned. If you try to open another archive with the same name on the desktop you will be asked if you wish to forget the old one. Details on the *OpenArchive command are given in the 'Commands' file and details on the open archive SWIs are given in the 'OldSWIs' and 'NewSWIs' files. The full archive pathname (inc. filing system) must be supplied when opening an archive. This is for three reasons: (1) If the archive filename is given relative to the current directory / filing system and these are changed, ArcFS will no longer be able to locate the archive. (2) If an attempt is made to open the same archive twice, once with the full pathname and once with a filename relative to the CSD, ArcFS will not recognise them as being the same. If both open instances are written to, then data corruption could occur. ArcFS will not normally allow an archive to opened more than once at any one time. (3) If a full pathname is not supplied, the 'open parent' menu option on ArcFSFiler will not work properly. When used on the desktop, the archive leafname should always be used as the archive name. In non multi-tasking software, it may be more convienient to use a fixed name for different archives. For example, if the program asks a user for an archive from which to fetch data, it could then open that archive with a standard name (e.g. 'SourceArc'). The archive(s) must be closed before the program exits. Archive Formats --------------- Archives produced by Spark and some PC archiver packages such as SEA arc or PKPAK can be opened and read from, but not written to. Files archived by the PC packages will all have filetype &FE4 (used by MultiFS for PC files). ArcFS archives can be read from and written to.
