Rambles/SplitS/ReadMe

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.

1  Introduction

   Splitf and Joinf were written to support the Acorn desktop application
   !Split. The purpose of these programs is to ease the transportation of large
   files from one computer to another. No attempt to compress the file is made,
   as it is assumed this has already been done. Splitf will split a file into a
   number of smaller files, and Joinf will join them again when required.



2  How To Use Splitf

   Usage : Splitf [options] <filename>

   Options supported are outlined below (they may be abbreviated):-

   -filesize n          Where n is the maximum size of each part in K (1024
                        bytes).

   -buffersize n        Where n is the buffer size in K (1024 bytes)�.

   -path p              Where p is the path (absolute or relative) to put the
                        parts.

   -interactive         This option allows you to specify a different
                        destination for each part. This is useful if saving
                        directly to several floppy disks.

   For example, if we have a file called 'Picture' 2 Mbytes long and we want
   to split it up to fit on two 1.44 Mb DOS formatted floppy disks. We would
   use the following command:-

   Splitf -f 1423 -b 1024 -i Picture

   This uses 1 Mb of RAM for a buffer�, and would prompt you for each path,
   allowing you to change floppy disks in between.

 � This option is not available on the PC version.



3  How To Use Joinf

   Usage : Joinf [options] <filename>

   -buffersize n        Where n is the buffer size in K (1024 bytes)�.

   -filename f          Where f is the new name of the file.

   -interactive         This option allows you to specify a different location
                        of each part.

   -info                This option just provides you with information about the
                        files without actually joining them.

   For example, if we want to join the two files in the above example, we would
   use the command:-

   Joinf -b 512 -i A:Picture01

   Note that A:Picture01 is the filename of the first part.

 � This option is not available on the PC version.



4  Compiling The Source Code

   To compile the source code, you'll need an ANSI C compiler. You must copy the
   config file to suit your machine, to 'config.h'. There are four supplied, if
   none of these match your machine, take a look inside them, it shouldn't be
   too hard to work out what the bits mean. If you have any problems just ask.

   I have provided executable files for a number of machines, just in case you
   don't have access to a compiler.



5  History

   � Version 1.00-1.08  These were the original command line versions compiled
                        on several different computers.

   � Version 1.10       This version has a new file format, a header is put at
                        the beginning of each part, and is used to join files in
                        the correct order. This version is compatible with the
                        desktop version (2.00 and greater).

   � Version 1.11       Slightly increased memory allocation for filenames, and
                        added a small check needed for DEC Ultrix compilers.

   � Version 1.12       Added -interactive option to allow direct reading and
                        writing of floppy disks. This option enables different
                        paths to be given for each part, removing the need, for
                        example, to load all the parts onto the hard disk before
                        joining.

   � Version 1.12c      Supports official Acorn filetype.

   � Version 1.13       Modified the Acorn specific bits to speed up file
                        access. Also tidied and commented the code a lot more.
                        NOTE: The only executables changed from version 1.12
                        are the Acorn ones, therefore I have only compiled
                        this version for these machines.
