                            4ZIP/4UNZIP User's Guide
                                  Version 1.03

                               Copyright (C) 1990
                                 I. J. Weinstein

        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.

             4DOS keeps a DESCRIPT.ION file in each directory. You should 
        know that this 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.  4UNZIP inserts file descriptions into this hidden file or
        creates a new one if necessary.

            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 
  1. 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


        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.
