-------------------------------------------------------------

PAK is  a  utility  to  create  and maintain file archives in
compressed form.  There are several advantages to compressing
files.   On  a   hard   disk,   most   files   are   accessed
infrequently.   Reducing  the size of these files allows more
of them to remain on the  hard  disk,  where  they  are  more
accessible than on a floppy in a file cabinet, and frees disk
space for other use.

Backup is  simpler,  faster, and cheaper, since the files are
smaller and organized into related groups.

Most importantly, compressed files take less time to transmit
via modem, and time is money when the  transmission  is  long
distance,  or to a service such as CompuServe.  Even on local
computer bulletin boards, reduced  transmission  time  is  an
advantage.

PAK is   intended   as   a  replacement  for  ARC  by  System
Enhancement Associates and PKARC and PKZIP  by  Philip  Katz.
While  PAK is faster than ARC, speed is not the emphasis, and
PAK does not attempt to compete with PKARC in  this  respect.
However, PAK produces archive files that are consistently 50%
to  90%  of  the size produced by either ARC, PKARC, or PKZIP
0.9 and supports files created  by  any  of  these  programs.
While  PKZIP  1.0 files are roughly comparable in size to PAK
files, PAK supports more archive formats and more features.

Finally, PAK is available in a full screen edition  which  is
much  easier  to  use  than  ARC,  PKARC,  or PKZIP, and in a
programmer's toolkit for those who want data  compression  in
their own programs.

Archive Files
-------------
PAK creates and modifies archive files, which have the  .PAK,
.ARC, or  .ZIP  extension.   An archive file may contain one,
two, or any number of compressed files.  Files in an  archive
retain all of the information they had in the directory, such
as  name,  size,  and  date.   In  addition,  each file in an
archive has  a  calculated  CRC  number,  which  assures  the
detection  of  damage  after events such as file transmission
via modem.

PAK 2.50  is  the  official  archive program for distributing
files  through  SDNet/Works!,  the   Shareware   Distribution
Network.   PAK will automatically recognize files distributed
by The SDN Project and SDNet/Works!  (sm).  The  SDN  Project
and   SDNet/Works!   is  a  cooperation  of  BBS  Sysops  and
not-for-profit.

SDN distributed files have the .SDN extension and a  Security
Envelope which   protects   them   from  viruses.   PAK  will
automatically check the  integrity  of  SDN  files.   If  the
archive  has been altered in any way, PAK will alert you.  If
the  archive  is  untouched,  PAK  will  display  a  page  of
information about the author.

Shareware authors interested in this free distribution should
contact The  SDN  Project  BBS  at 203-634-0370, 1200-9600HST
baud, 8-N-1.
