Zip Vs. PKZip
Zip includes path information in the archive by default. PKZip does not.
Zip recurses directories by default (if path wildcarded). PKZip does not.
Notes:
Comparing the freeware Zip program to Phil Katz’s PKZip V2.04G:
The freeware Zip program will store path information in the archive by default.
For PKZip, use the “-p” or “-P” options.
The freeware Zip program will recurse directories by default if the path is wild-carded.
For PKZip, use the “-r” option.
