Several new features have been added to PKZIP/PKUNZIP/PKSFX
version 2.04c.  Read the file ADDENDUM.DOC for a complete
description of these changes and enhancements.  Highlights
of PKZIP/PKUNZIP/PKSFX etc. version 2.04c include:

-Improved Compression

       PKZIP/PKUNZIP 2.04c implements a new compression algorithm
       called Deflating.  Deflating has varying levels of compression
       and speed available.  Both speed and compression are greatly
       improved over previous versions of PKZIP.

-Multi-Volume Archive Support/Formatting

       PKZIP/PKUNZIP 2.04c has the ability to "span" a .ZIP file across
       multiple diskettes if the final .ZIP file size would be greater
       than a single diskette.  PKZIP 2.04c also has the ability to
       format the destination diskettes on the fly.

-XMS/EMS Usage

       PKZIP/PKUNZIP 2.04c has the ability to use of EMS, UMB, and HMA
       memory, which will allow the ability to process more files or be
       able to run with less conventional memory.  PKZIP/PKUNZIP 2.04
       will run in as little as 85K of conventional memory if EMS or
       XMS memory is available.

-Novell Network Aware

       PKZIP 2.04c is Novell Netware "aware".  Updating or creating
       a .ZIP file on a network drive is much faster with the network
       support in PKZIP 2.04c.

-Auto CPU type detection.

       PKZIP/PKUNZIP 2.04c will detect what type of CPU it is being run
       on and will use instructions specifcally optimized for an 808x
       CPU, 80386 CPU, or 80486 CPU.

-DPMI support

       PKZIP/PKUNZIP 2.04c automatically detects if DPMI (DOS Protected
       Mode Interface) support is available and will execute code in
       32-bit protected mode for better speed.

-PKCFG program

       PKZIP 2.04c can be configured to best suit your needs through
       the use of the PKCFG program.  This is only available in the
       registered version of PKZIP.

-PKSFX Junior and PKUNZIP Junior

       These "Junior" programs use very little memory and are extremely
       small.  Although they are reduced in ability, their small size
       makes them very useful.

-Password Encryption

       Sensitive data files can be scrambled with password protection.
       The security of this feature has been significantly improved in
       PKZIP/PKUNZIP 2.04c.

-Authenticy Verification

       Users requiring authentication of archive files may request an
       Authenticy Verification code.  This allows users to create .ZIP
       files which PKUNZIP can detect tampering of.
