Since I recently got the latest versions of PKZIP (1.01) and PAK (2.10), two of the high-end MS-DOS archivers, I decided to put this little file together, which is based on another comparison I did about a year ago with older software. It should be able to give people an idea about the differences in the various IBM PC archiver programs in 3 areas - "shrinkage", speed of compression, speed of extraction. Enjoy. -------------------------------------------------------------------- Erik Talvola's MS-DOS Compression program test Release of 8-25-89 Copyright 1989 by Erik Talvola. Do whatever you want with this file, except remove this message from it. comments/suggestions/complaints to: talvola@janus.berkeley.edu ...!ucbvax!janus!talvola These are some simple benchmarks I did with all the compression/archive type programs I have (i.e., programs which do both compression and archiving as one step. This excludes such combinations as TAR along with Compress, or the old CP/M LBR with SQ).
