ZIPSPLIT Split Utility for PKZIP (tm) Version 1.2 08-27-92
FreeWare (C) 1990-1992 Jon Harald Holm
ZipSplit split ZIP files into smaller ZIP files. This is useful when
taking backup of large ZIP files onto floppy disks.
ZipSplit is FreeWare. Anyone is allowed to use ZipSplit for free and
at own risk (ZipSplit is not guaranteed to be bug free). You don't
have to pay me anything! Please distribute ZipSplit as the original
ZIP file and take no more than a nominal charge for handling only (no
profit).
Do you have any comments?

zipspl30.pif PIF file for Microsoft Windows 3.0
zipspl21.pif PIF file for Microsoft Windows 2.1
Installation:
-------------
You can copy the files anywhere you like. ZipSplit don't need any
environment variables.
If you want to use a PIF file, remember to edit the 'Program Filename'
in the PIF Editor. I recommend you rename the PIF file you want to use
to ZIPSPLIT.PIF.
Usage:
------
If you just type zipsplit ('Enter'), you will get this output:

ZIPSPLIT Split Utility for PKZIP (tm) Version 1.2 08-27-92
FreeWare (C) 1990-1992 Jon Harald Holm ZIPSPLIT for help
Usage: ZIPSPLIT source[.ZIP] target {[size|disk]}
source = name of file to split
target = target filename
size = split size in kB
disk = one of the predefined disk sizes; D360 D1.2 D720 D1.4
----------------------------------------------------------------
Maybe this is not enough help in the beginning, so I will explain each
argument in detail.
source:
This is the source filename. If you don't include any extension,
ZipSplit assumes the extension to be ZIP. The filename may include
wildcards.
target:
The target may consist of a drive, a path and a filename. Where the
drive and path (if included) indicates where to store the files. The
filename is the name you want to give your split files. Each split
file will get a number in the end of the filename to distinguish them
from each other. Your name will be truncated to give room for this
number if necessary. If you don't include any extension, ZipSplit
will add ZIP.
size:
If you use this argument, then you can't use the 'disk' argument.
'size' is a number which indicate the size in kB of each split file.
disk:
This is just a predefined size. It is used to split in sizes which
fits exactly onto diskettes, e.g. you want to store the files on 3.5"
HD diskettes, then you choose D1.4 as argument.
You may give as many size|disk arguments as you like. ZipSplit will
make a split file for each size. The last size|disk argument will be
the default size. The default size is used when a split file is made
for each size|disk argument but still more split files are needed.
E.g. 'zipsplit test test d720 d1.4' will give one file which fits a
720 kB floppy and the rest of the files will fit 1.44 MB floppys.
If you don't use 'size' or 'disk', then all available space on the
target disk will be used.
When the target disk don't have any more space, you will be prompted
to change floppy disk or you may type in another target disk letter.
Examples:
---------
I will give two examples to remove any doubts about the use of ZipSplit.
1) Split the file to the C drive in chunks that fits 720 kB floppy disks:

2) Split the file to the diskettes in the A and B drive:

Either enter the name of another target disk drive or if the
target disk is a floppy, insert a new floppy. Then press 'Enter' => b

3) B:TEST3.ZIP

-------------------------------------------------------------
Miscellaneous:
--------------
ZipSplit can't split ZIP files to whatever size you want. This is
because each file inside the ZIP file must be in one file. If you
want to split into 100 kB files, and one file in the ZIP file is 110
kB then one split file will be bigger than 100 kB. Ref. "Program
messages" below.
ZipSplit will store the largest file in a ZIP file first. If you
split to diskette and don't use any size argument, use the diskettes
with largest free space first.
The 'Fill' message after each ZIP file indicate how many percent of
the given size (rounded up to nearest 1024) have been used. Did you
not give any size, this percentage indicates how much of the disk free
space you have used.
If you add the sizes of the split files, you will see that it is
larger than the size of the original file. This is because each split
file is a ZIP file, and includes the ZIP format data.
Program messages:
-----------------
* Not enough space on target disk!
Either enter the name of another target disk drive or if the
target disk is a floppy, insert a new floppy. Then press 'Enter' =>
The target disk is full! Is it a floppy then you may change floppy
and press 'Enter'. Otherwise you can type in a new drive letter and
press 'Enter'.
* Can't be made smaller
The ZIP file include a file which is larger than the size given.
(See miscellaneous.)
* ERROR: File <file> not found.
ZipSplit can't find the source file. Check if the path is correct spelt!
* ERROR: Undefined argument size.
The last arguments on the commandline can't be recognized as a number
or as a predefined disk size.
* ERROR: <file> is not a ZIP file.
The source file can't be recognised to have the ZIP format.
ZipSplit can only split ZIP files, but the extension don't have to be ZIP!
* ERROR: Not enough memory.
The amount of memory ZipSplit uses depend on the number of files in
the ZIP file (not the size of the ZIP file). If you get this error
message, then I suggest you manually split the file in two (pkunzip,
pkzip) and then use ZipSplit.
* ERROR: Can't open file <file>.
ZipSplit can't open the source file! ZipSplit reads the source file
twice. You get this message if you remove the source file after it
was located the first time.
* ERROR: Target disk failed.
ZipSplit can't estimate the free space on the target disk. Something
must be wrong about the disk (drive)!
* ERROR: Can't create file <file>
ZipSplit can't create the target file.
* ERROR: Can't close <file>
ZipSplit can't close the target file.
