ZIPPER.DOC
ZIPPER.. by the Bytebrothers
J.L. Pearson
Zipper is designed to let you easily and quickly convert
any and all .ARC and .PAK files to the to the new Phil Katz
ZIP format using PKZIP. Place ZIPPER in the directory that
you keep PAK.EXE, PKUNPAK.EXE and PKZIP.EXE in. ZIPPER will
automatically sense .ARC or .PAK formats and uncompress them
and convert them to Phil Katz's new .ZIP format. It operates
on one file at a time in automated fashion and deletes the
original file after verifying the unarchive operation.. The
original file date and time are preserved in the new .ZIP
file.
Before you rush into conversion read the READ.ME file or the
note below on correctly installing the PAK.EXE program from
NoGate Technology.. It can be dangerous when run uninstalled.
Here are some examples of usage..
ZIPPER c:\arcs\*.pak
this will convert all the .PAK files in directory C:\arcs
into .ARC files. The original .PAK files will be deleted so
when ZIPPER is done the .PAK's will be transformed into
.ZIPs.. If you have a number of .ARC's and .PAK's mixed in a
directory named C:\com the following commands can be used..
ZIPPER c:\com
this will change all the .PAK and .ARC files so that when
done directory c:\com will have nothing but .ZIP files..
ZIPPER c:\com\*.arc
this will change all the .ARC files to .ZIP but leave the
.PAK files intact.. C:\COM will have only .ZIP and .PAK files
in it..no .ARC's.
Let's say you run a bbs and have a directory full of .ARC
files you want to change to .ZIP.. The directory name is
C:\bbs\dl1. Enter the following..
ZIPPER c:\bbs\dl1
ZIPPER will go to dl1 and since it is full of .ARC files it
will convert every one into a .ZIP file. Entering a directory
with no filenames is the same as \*.* and all files will be
converted. Notice that if the directory has both .ARC and
.PAK files they all will be converted to ZIP. Any .GIF, .MAC
or other extension files are always ignored..
ZIPPER.DOC Sunday, February 5, 1989 10:25 pm Page 2
If you have only one file to convert just enter the filename
as in ZIPPER c:\bbs\dl1\pascal.arc The file PASCAL.ARC will
be converted to PASCAL.ZIP.. as simple as that..
There is only one requirement for setup on ZIPPER. You must
set an environment variable SPAT to the path of your archive
utilities.. PKUNPAK.EXE, PAK.EXE and PKZIP.EXE.
example.
set spat=c:\utility
will tell ZIPPER to look in directory C:\UTILITY for the
archving files. And to use this directory to store his config
file and the badfile list..
This command can be placed in your autoexec.bat file and
ZIPPER will automatically be set up every time you boot..
if you should get an error " out of environment space " when
you boot use the command..
shell=command.com c:\ /e:1024 /p
Dos 3.3
or
shell=c:\command.com /e:1024 /p
Dos 3.2
in your CONFIG.SYS file.. using the drive that you boot from
and where your copy of command.com is located. This will
increase your environment area to 1k bytes but will not work
on early versions of DOS. Most later versions will accept
either command..
ZIPPER will also use this path to create it's own
configuration file the first time you run it. You can modify
this file ZIPPER.CFG to reflect your unarchive command ( if
you have modified the commands in PAK.EXE ), the name you
want to call PKUNPAK ( ie. PKXARC etc.. ), and the actual
commands you send to PKZIP setting the level of compression.
Defaults are provided in the ZIPPER.CFG file for standard
operation at ZIP's highest compression level.. ZIPPER will
also use this directory to create a BADFILE.LOG file that
lists any and all .ARC or .PAK files that were bad and failed
to uncompress.. Make sure that you set PAK up right. Read the
notes in the READ.ME file or below under the heading
IMPORTANT on running the PAKINSTAL program on PAK.EXE.. He
can be dangerous if he is not installed correctly and you use
him outside of his home dir. With the SPAT variable set and
PAKINSTAL run on your copy of PAK.EXE ZIPPER will run from
any drive or directory as long as he is in your path..
ZIPPER.DOC Sunday, February 5, 1989 10:25 pm Page 3
operation..
ZIPPER converts a file at a time and creates a .\SWORK
subdirectory under your current directory to work in. The
work directory is deleted when done..if there is an abort or
error during compression of an already unarced file the
program will prompt you, so if you want you can save the work
directory data.. The work directory will contain the last
unarced file's contents if a file has been unarced and not
repacked... Any errors encountered with bad arcs are handled
by inserting the time,date and pathname of the bad .ARC or
.PAK file into the file BADFILE.LOG and ZIPPER goes onto the
next file.. ZIPPER will abort cleanly if you press escape..
ZIPPER saves the original date and time of the file and
touches the new .ZIP file, so the original file date is
preserved.. and you don't wind up with all your directory
files dated the day of the conversion..
ZIPPER creates a file in your SPAT directory called
BADFILES.LOG. Everytime you run ZIPPER it places the time and
date of the run in the BADFILE.LOG file as well as any files
it finds which fail to unarchive.. here is a sample of the
file..
ZIPPER badfiles Sunday February 5, 1989 time 8:40:26 p.m.
d:\arcs\hold\mona.pak
d:\arcs\hold\nc12.arc
d:\arcs\hold\nc13.arc
ZIPPER badfiles Sunday February 5, 1989 time 8:53:25 p.m.
d:\arcs\hold\mj12.pak
d:\arcs\hold\mono.arc
d:\arcs\hold\mj12.arc
Registration of ZIPPER will give you a version that will
automatically delete all the bad files at the end of
operation.. and also has a batch switch to run without any
user intervention from a batch file.. I am not trying to
cripple ZIPPER but I am not going to hassle with any mods if
no one is interested in registering it..
Entering ZIPPER with no arguments will bring up a help screen
and then prompt you for a further filename.
IMPORTANT:::::::::::::::::::::::::::::::::::::::::::::::::::
PAK can be dangerous in that if you want to run it outside
the current directory you need to run a program called
PAKINST to install it and tell it where it's CNF file is
located. This install program is in the .PAK arc ( ie.
PAK151.ARC or PAK16.ARC ) but it's use is documented in the
ZIPPER.DOC Sunday, February 5, 1989 10:25 pm Page 4
back of the docs and many people miss it. PAK can do some
very undesirable things if it is used outside it's home
directory without being installed.. Make sure and run PAKINST
and tell PAK where it's config file is before you use the set
command with ZIPPER and start using it outside of the PAK.EXE
directory..
If you appreciate and use this program please send $15 for
registration to..

With registration you will be sent the latest revision of
ZIPPER which will have two command line switches.. One will
automatically delete all the bad arcs at the end of the
conversion.. the other switch will cause ZIPPER to run
without user prompts for automated operation from a batch
file..
I will not be held responsible for any damage caused by this
program.. it is distributed as is. Care should be taken to
insure enough disk space to do the conversions. A tightly
packed floppy with PAK files can not have enough room to hold
the larger loosely compressed .ZIP files. The program will
abort when the disk is full and the last unarchived file will
be in the work directory.. The program has been tested on
many computers and if your computer will run PK and PAK and
you have correctly INSTALLED your PAK.EXE program you should
have no problems..

a note..
We have all waited some time during the debacle between Phil
Katz's PKWARE vrs. SEA hassles. Phil has lost his PK code and
gone back to sqaure one while SEA's releases have found
remarkable new performance.. Phil has noted in his ZIP
release that the extension ZIP is released to the public
domain.. unlike SEA's attitude on ARC. I think this about
sums it up.. SEA now has the right to use ZIP on it's
tombstone and Phil can't complain let alone sue.. The worm
has turned folks..get Zippin.. ..R.I.P. ARC..!
