Documents/DirSelect

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.

ArcFS 0.50/2.00 Documentation
-----------------------------

User Root Directories (U.R.D.'s)
--------------------------------

Use *URD to select the user root (&) directory. If the URD is "unset" then
the root ($) directory is used instead.

The previously selected directory (P.S.D.)
------------------------------------------

When a new directory selection is made, the old one becomes the P.S.D. Use
*Back to swap the C.S.D. and P.S.D. The P.S.D. can be specified at the
begining of a pathname as \. If the PSD is "unset" then the CSD is used
instead.

Automatic library selection
---------------------------

If ArcFS finds a directory starting with the letters 'Lib' in the root
directory of an archive when it is open it selects this as the library
directory.

Unset Directory contexts
------------------------

If the PSD or library are used but are "unset" then the CSD is used instead.
If the URD is "unset" then the root is used instead. If the CSD is "unset"
and the user tries to perform operations on the current directory (or
current archive) the an error will be generated.

If the CSD is "unset" and an archive is opened, the CSD will automatically
be set the root directory of the new archive.
