Split! 1.0
User Manual
December 11, 1993
INTRODUCTION
Frequently, I had to move large files between platforms. When I
had a 10 megabyte file on my Amiga hard disk that I wanted to take
to school (an IBM network) for printing, I found that when I LhAed
the file, it still wouldn't fit on a floppy disk. After trying
other file splitters, I found that they were just too slow for my
needs. I wrote my own.
INSTALLATION
Split! is a CLI-based command, and therefore should be placed
somewhere in your command path. I reccomend that you move the
executable to your C: directory before use.
USAGE
Split! must be run from the CLI, and takes only two parameters:
Split! <infile> <outfile>
<infile> is the large file you want to split up into smaller files.
<outfile> is the root of the destination filename. For each file
created, a numerical extention will be added.
Once run, Split! will ask you how big (in Kilobytes) to make each
<outfile>. To transport it on standard MS-DOS 720k disks, I would
reccomend a split size of 700. For 1.44Mb MS-DOS disks, enter 1400.
Example:
Split BigFile LittleFile
SplitSize (Kb): 700
The files would be called: LittleFile.1, LittleFile.2, etc.
On the MS-DOS system, you just copy all the files off the disks
into a directory on the hard disk. The MS-DOS 'COPY' command
does a good job of putting them back to gether.
COPY LittleFile.1/b+LittleFile.2/b+LittleFile.3/b BigFile
This would join all the smaller files into a larger one called
'BigFile.' The '/b' switch on each file is important. It tells
COPY that it is joining binary files, and thus will not stop at
the first CTRL-Z it sees.
BENCHMARKS
These tests where done with the file NodeList.316, the FidoNet
nodelist. The source file was 2212118 bytes long. The splitsize
in both cases was 700k.

LIMITATIONS
Alas, the programs speed is not a result of my programming
prowess. It is simply because of my big-assed buffer! By
processing 32k at a time, your systems hard disk has to seek
less. Unfortuantely, this is demanding on _very_ low memory
systems. I would have included my PCQ Pascal source code,
but I'm too embarrased.
DISTRIBUTION
Although this program is freely distributable, it remains _my_
program, Copyright (c) Dan Fraser, 1993.
I shall impose a few limitations on distribution. It must not be
_sold_ for profit. It must not be placed in public domain
collections for which more than $4 a disk is charged, and it may
not be used in commercial product distributions without my written
permission.
