The world of data compression is continually growing and evolving. Since the founding of PKWARE in 1986, compression has been a necessary tool for the computer user. Although the uses for our compression products have grown and changed over the years, the fundamental need for reliable compression is as strong as ever.

PKZIP was PKWAREs response to the compression needs of the computer market. PKZIP not only introduced the .ZIP file format to the public for the first time, it also brought a reliable alternative to the plethora of compression utilities on the market in the late 1980s.

The author of this web site has been using the command line version of PKZIP to do a compressive incremental backup. (see example below) This is backup procedure that backs up only those files that have been modified since the previous backup. Contrast with an archival backup, in which all files are backed up regardless of whether they have been modified since the last backup.

Why Use PKWARE ?

WINZIP is the defacto industry standard decompression tool. Since PKWARE and WINZIP are sourced from the same company, they are 100% compatible.
WINZIP can completely reconstruct the disk directory structures from the archive with path type archive
WINZIP is easy to use and everyone knows how to use it already. Hence, nothing to learn anew!

path

     store directory path names for files within a .ZIP file



AVAILABLE VALUE(S):

     current (default) - stores the path from the current directory

     root/full  - store the entire path beginning at the root of
                  the drive; also referred to as 'full' path

     relative - store subdirectory name and path structure information
                relative to the specified directory. This includes
                subdirectory name and path information for files below
                the specified directory. The specified directory's name
                and path information is not preserved.  (This option is
                not available on Unix platforms.)

     none  - no path information stored; turns off path option
             in config file
                subdirectory name and path information for files below
                the specified directory. The specified directory's name
                and path information is not preserved.  (This option is
                not available on Unix platforms.)

     none  - no path information stored; turns off path option
             in config file


EXAMPLE USAGE:

Assuming in you are in the path '/etc/usr'

     pkzip25 -add -path=root save.zip  /etc/usr/*

       (the path stored would be '/etc/usr/')

EXAMPLE USAGE:

To include password in the command:

     pkzip25 -add -pass=baseball save.zip

To have PKZIP prompt you for a password 'after'
you type the command:

DIR Syntax

Displays a list of files and subdirectories in a directory.

DIR [drive:][path][filename] [/P] [/W] [/D] [/A[[:]attributes]] [/O[[:]sortorder]] [/T[[:]timefield]] [/S] [/B] [/L] [/N] [/X] [/C]

  [drive:][path][filename]
              Specifies drive, directory, and/or files to list.

  /P          Pauses after each screenful of information.
  /W          Uses wide list format.
  /D          Same as wide but files are list sorted by column.
  /A          Displays files with specified attributes.
  attributes   D  Directories                R  Read-only files
               H  Hidden files               A  Files ready for archiving
               S  System files               -  Prefix meaning not
  /O          List by files in sorted order.
  sortorder    N  By name (alphabetic)       S  By size (smallest first)
               E  By extension (alphabetic)  D  By date & time (earliest first)
               G  Group directories first    -  Prefix to reverse order
  /T          Controls which time field displayed or used for sorting
  timefield   C  Creation
              A  Last Access
              W  Last Written
  /S          Displays files in specified directory and all subdirectories.
  /B          Uses bare format (no heading information or summary).
  /L          Uses lowercase.
  /N          New long list format where filenames are on the far right.
  /X          This displays the short names generated for non-8dot3 file
              names.  The format is that of /N with the short name inserted
              before the long name. If no short name is present, blanks are
              displayed in its place.
  /C          Display the thousand separator in file sizes.  This is the
              default.  Use /-C to disable display of separator.

Switches may be preset in the DIRCMD environment variable.  Override
preset switches by prefixing any switch with - (hyphen)--for example, /-W.

example:

dir c:\*.* /s /o-d >sorteddir.txt 'sort in reverse order, newest first
