Is PKZIP version 1.10 available for posting? If so, could someone please uuencode it and either post it or mail it to me. I have an older version and saw an article in PC Week which compared version 1.10 to other compres- sion utilities. If it's no longer available via BBS, how should I get the new one? -- Kevin Routh (routh@eltanin.rtp.semi.harris.com) Harris Smart Power Products, Durham, NC (919) 361-1622

The PC Week article did not test using ZOO, which has been around for ages, which i thought was surprising. They also did not test using LHARC which is public domain and comes with complete source code AND has better compression than pkzip in *most* cases. It's as usual. People doing these "benchmarks" are way behind on whats going on. BBS: 301-972-6131 HOME: 301-972-2310 UUCP: ..uunet!ocsmd!stsim!glenn

It is too bad they chose to ignore ZOO, since it's available on the widest variety of operating systems; on the other hand, it's quite slow and has only mediocre compression, so it's perhaps not such a great loss for a PC magazine to pass over it. LHARC, btw, is NOT public domain, at least as of the last version I saw; the Unix version is copyrighted by Yooichi Tagawa, and I'm pretty sure the PC version is as well. It is free, however. And it's been my experience that PKZIP almost always manages better compression, although the actual archive may end up larger (especially if it contains many small files) due to the greater amount of overhead PKZIP stores (pathnames, comments, you-name-it). The two programs are generally within a few percent of each other, though. And, of course, if you're working on a Unix system, LHARC is infinitely more efficient. :)

It is free, however. Bear in mind that Glenn, like most people, thinks "public domain" means "software the author doesn't expect you to pay for." Since definitions in the end comes from usage, that'll probably be the standard definition before long. In any case, I've long since given up correcting people on this point. To anticipate all the people who'll correct *me*: some free software *is* public domain, but the terms aren't synonymous. Public domain means lacking copyright or other legal protection. People who give away software often copyright it, to prevent others from selling it or providing versions with unauthorized changes, or to protect future commercial versions, or their exclusive right to publish the source code in a book, and so on. At least that's the legal definition; as I said, usage always has the final say in the end. > And it's been my experience that >PKZIP almost always manages better compression, although the actual archive >may end up larger (especially if it contains many small files) due to the >greater amount of overhead PKZIP stores (pathnames, comments, you-name-it). >The two programs are generally within a few percent of each other, though. I know a sysop who (just after the ZIP/ARC wars) went to LHARC because of that few percent. (He has nearly a gigabyte of files, so even a small savings was worth it to him.) But he finally switched to ZIP because, I gather, he needed more support than he could get from a non-commercial product.

I also moved to LHarc with my BBS (in Alaska, and now defunct since I moved south) because of the advantage in size. However, when version 1.10 of PKZIP was released, the difference in size shrank to such a small margin that PKZIP's faster compression and decompression became more important. I didn't delete LHarc, though... it still produces the smallest self-extracting file. -- ____________________________________________________________________________ Roy M.

Funny thing... You can dial up most BBS in Australia and get a copy, complete with the message about not exporting it from the states. P.S. Does that mean I could post it to the net? :-)
