A.BACKGROUND
4DOS provides a way of attaching descriptions to files
on your disk that is apparently seamless. The descriptions
appear on directory displays and automatically are copied
when you COPY or MOVE a file to another disk or directory.
But this seamless property fails as soon as you use other
programs on your files. For example, if you archive the files
with the PKware programs PKZIP or PKUNZIP, the descriptions
stay behind. 4ZIP and 4UNZIP address this problem, providing
an automatic method to store descriptions in ZIPFiles and to
restore them when you extract a file.
You should know that the DESCRIPT.ION file is a hidden file.
You will not see it in the DOS directory unless you change the
file attribute or use the 4DOS DIR /h option.
You must have copies of the PKware utilities located on the
DOS Path, or in the current directory. These shareware programs
are not supplied with 4ZIP/4UNZIP. You can obtain them from many
Shareware distributors, BBS's or from PKware directly at:
PKware Inc.
7545 North Port Washington Road
Glendale, WI 53217
XD Systems is not affiliated with PKware in any way.
B. 4ZIP USAGE
4ZIP Usage is:
4ZIP ZIPFILE [/am?] [d:][path][filespec] [+filespec] [+..]
A directory display similar to that of SELECT will appear
showing all of the files meeting any of the filespecs. This
use of include lists is identical to the 4DOS 3.0 DIR and
SELECT usage. Note that only the first argument in an include
list can have a pathname; subsequent arguments default to the
same path.
You can mark files to be ZIPped into ZipFile in several
ways, similar to the 4DOS SELECT command, as follows:
<+> MARK file
<-> UNMARK file
<space> Toggle MARK
<*> MARK all files
2
To move the selection bar around the list of files, use
the following keys:
<UP> Move up one line
<DOWN> Move down one line
<PgUp> Move up one full screen
<PgDn> Move down one full screen
<HOME> Move to top of list
<END> Move to end of list
When you are finished marking files, then:
<ENTER> ZIP marked files into ZIPFILE
<Esc> Quit 4ZIP without doing anything
4ZIP also has two options, which can be used singly or
together, e.g., /a /m, or /am.
/a ZIP all files matching filespecs without query.
4ZIP Junk /a C:\SOURCE\*.Pas + *MATH*.INC
would ZIP into JUNK.ZIP all files from the C:\SOURCE
directory that either had the extension PAS or the
extension INC and MATH anywhere in the filename.
/m Move selected files from source directory to the ZIPFile.
This works by deleting the files from the source
directory after ZIPping.
C. 4UNZIP USAGE
4UNZIP Usage is:
4UNZIP ZIPFILE [/adm?] [outpath] [d:][path][filespec] [+filespec] [+..]
The display is identical to the 4ZIP display, showing
all the files in the ZipFile that meet any of the filespecs.
Marking of the files to be extracted and cursor movement
around the screen is identical to 4ZIP.
4UNZIP has three options. The first two are similar to
the ones provided for 4ZIP.
/a UNZIP all files matching filespecs without query.
/m Move selected files from the ZIPFile to the outpath
directory (Current directory is default).
/d Delete selected files from the ZIPFile without extracting.
This provides a convenient tool for ZipFile management,
allowing you to select files to be removed using any
3
combination of filespecs with wild cards and the SELECT screen.
The combination /ad will delete all the specified files
without presenting the SELECT screen. The combination /md
is interpreted the same as /m alone.
Outpath, if supplied, determines the directory in which the
extracted files are to be placed. So for example
4UNZIP C:\SOURCE\JUNK A:\ /am *.doc
would extract all of the files with extension doc from the
file C:\SOURCE\JUNK.ZIP and place them in the root directory
of the A: drive. Then it would delete all of these files
from JUNK.ZIP.
C. REGARDING REGISTRATION

D. 4ZIP/4UNZIP VERSION HISTORY
Ver 0.90 (Beta Test) 12/01/89
This is the original release. It used batch files to drive
4ZIP and 4UNZIP and could only run under 4DOS.
Ver 0.91 (Beta Test) 12/20/89
4ZIP and 4UNZIP now stand alone, and can be run under DOS. 4UNZIP
accesses the ZipFile Directory itself without using PKZIP -v. This is
much faster.
Ver 0.92 (Beta Test) 1/21/90
Improved exception handling for DOS errors.
Added /d and /m options to 4UNZIP
Allow specification of destination path for the extracted files in 4UNZIP
Ver 0.93 (Beta Test) 2/04/90
1. Changed mark/unmark in 4ZIP and 4UNZIP to be more like the latest
SELECT. Space bar toggles mark and * marks all.
2. 4ZIP lost descriptions on some files in big directories. Now
fixed.
3. Ver 0.92 of 4ZIP tried to correct command line parser so that
C: ==> C:*.* and ABC ==> ABC\*.* if ABC is a directory but
ABC.* otherwise. Got it right this time!
Version 1.0 3/11/90
First public release
Version 1.01 3/21/90
1. Corrected error (shame on me) in 4UNZIP that included marker
in filename.
2. Corrected 4UNZIP error when destination path is not source path.
3. Minor changes in documentation.
Version 1.02 3/23/90
Corrected error in 4ZIP and 4UNZIP - not properly recognizing
include lists.
Version 1.03 4/01/90
Changed file access to run on networks reliably.
Added name and serial number on registered copies.
Version 1.04 6/10/90
Modified to correct for 4DOS 3.0 quirk. Entries in DESCRIPT.ION
are sometimes delimited by LF instead of CRLF. Earlier versions of
4ZIP/4UNZIP misread these lines.
Corrected 4ZIP/4UNZIP to properly access ZIPfiles smaller than
150 bytes.
5
Version 1.05 7/15/90
Corrected error that caused -a option of 4UNZIP to lose
descriptions.
Version 1.06 8/03/90
Added Error Messages for Drive unready and Disk write-protected.
4ZIP JUNK a: is now equivalent to 4ZIP JUNK a:*.*
Version 1.07 9/16/90
4UNZIP choked on the long ZipFile comments now being added by some
BBS operators. Modified to correct this.
Version 1.08 10/18/90
4UNZIP occasionally dropped file descriptions if the file had an 8 character
name and a 3 character extension. This is corrected. A problem with include
lists that caused the same file to be selected more than once has been
corrected for both programs. For example, 4ZIP test *.txt+4*.txt would show
the file 4zip.txt twice.
E. 4EDIT
Also take a look at 4EDIT, a full-screen editor for dir-
ectory comments (or, in 4DOS terms, Descriptions). I think you
will find it very useful. Its good practice to comment your
files, and often its handy to see the descriptions attached to
other files, while you are writing a new one.
The 4EDIT package is shareware, available on Bulletin Boards
and from shareware distributors. Registration is $15. See the order
form at the end of this manual.
