The 1.01 version added a new type of compression, called "Imploded"
files. (the extraction, of course, is called 'Exploding') As best as I
can tell, the Imploding technique stemmed from Phil Katz' adaptation of
some of Yoshi's techniques in LHarc. The adaptation went very well...
many times, PKZ102 will pack a file tighter than LHarc. (LHarc still
does better with Self-Extracting archives, though, because the SFX
header is so much smaller [1322 bytes])

PKZ092 will look at a 101 zipfile, but it will report Imploded files as
compression type 'unknown'. Attempts to extract them will result in the
message "Don't know how to handle 'filename'".

Of course, PKZ101/2 will handle 092 files just fine. The 102 version did
have some bug fixes, but the docs say the fixes were for 286/386
machines, and had to do with some esoteric memory handling peculiar to
the advanced architecture.

The REZIP package was included with the PKZ102 I have. There is also a
package called ZIPKIT8 that has some handy Zip-handling utilities, such
as for adding comments from a file. (handy if you run a bbs, as you can
easily add a standard comment to all your downloadables)

Hope this all helps......
