                    XADFS - The ADFS diskimage extractor
                    ------------------------------------

 XADFS is a small program I wrote to transfer files from my Acorn Electron
to my PC, as my two Electrons haven't got a serial interface (RS423).

 The procedure is simple: Put an Electron Plus-3 ADFS disk in your PC's
diskdrive, run a diskimage-making program (such as Anadisk) and save the
data in a "raw" format, i.e. without additional sector info and such, to
your harddisk. Then run this program with the filename of the image as a
parameter.

 Every Acorn file will be extracted to TWO pc files, with the first eight
characters of the Acorn filename as the PC filename. One contains the data,
the other file (with the extension .INF) contains information in Wouter
Scholten's format. So, suppose your Electron disk contains a file !BOOT,
on your PC you'll get these two files: !BOOT and !BOOT.INF.

 An Acorn file may have a name with up to 10 characters, so saving it by using
the first 8 of the name as a PC filename might overwrite another file. Say
you've got the file AAAAAAAAAA and AAAAAAAAAB, they would both be saved under
AAAAAAAA and AAAAAAAA.INF. Of course you don't want this, so XADFS
automatically saves the first as AAAAAAAAAA and the second as AAAAAAAA~0.

 Please bear in mind that I've only tested it once, on a diskimage of a
320K ADFS disk (Electron Plus-3) made by Anadisk. I hope it'll work for other
disksizes (160K and 640K) as well, but I don't know for sure. If you discover
an error, please inform me by email so I can improve the program.

 Greetings and good luck with the program, hopefully it proves useful to
somebody besides myself...
