Here are a few anticipated questions and their answers:


Q: You recommend use of the "/b" (use both PKZIPs) option.  Why?

A: Take a look at the table in "SMARTZIP.DOC".  Some files compress MUCH
   better with the "Reducing" algorithm, which is available ONLY in
   PKZIP 0.9x.  In fact, MUCH of the benefit of using SmartZIP comes
   from using the Reducing compression algorithm when appropriate.


Q: But won't I always get the best possible compression using the "-ex"
   option in PKZIP 1.xx?

A: No.  Since some files compress best with Reducing, which isn't
   available in PKZIP 1.xx, you can't always get the best compression
   with PKZIP 1.xx's "-ex" option.  Even if a particular file compresses
   best with either PKZIP 1.xx's Imploding or Shrinking algorithms,
   PKZIP 1.xx doesn't always select the best of the two for a particular
   file.


Q: What do I need to do to use the "/b" (use both PKZIPs) option?

A: Leave PKZIP.EXE for PKZIP 1.xx alone.  Take the PKZIP.EXE for PKZIP
   0.9x and rename it to "PKZIP09.EXE".  Both of these .EXEs should be
   in a subdirectory specified in your PATH.  Then, just use the "/b"
   option switch when you run SmartZIP.


Q: But, I've already deleted PKZIP 0.9x!  What can I do?

A: PKZIP092.EXE (the file containing the PKZIP.EXE for PKZIP 0.9x as
   originally distributed by PKWare) is still available on many BBSes,
   including Exec PC in Milwaukee.  See the contact information in
   "SMARTZIP.DOC" for Exec PC's phone number.  Another possibility is to
   contact PKWare and ask for it.  Perhaps with enough requests, it'll
   be made available directly from PKWare.  As a last resort, contact
   me.  I'll tell you where to get it.
