Subj: SOMEONE JUST OUTDID ZIP! Status: PUBLIC MESSAGE
Well, guess what showed up today on GEnie, courtesy of one of
our Japanese users....
A completely PUBLIC DOMAIN, FREE, NO DONATIONS REQUESTED new
archive compression program. It's called LHARC and it was just
uploaded a few days ago by one of our NEC PC-VAN Japanese users.
"So what?" you may say... Read on.
LHARC compresses files up to 15 percent better than anything
PKZIP has been able to produce so far, even when using -eb4 and
-ea4. No, I'm not kidding. It's better than ARC, ZOO, PAK and
ZIP put together. We are running preliminary tests on it, but it
looks like it beats ZIP by a mile, not to mention other
utilities available out there. It's slower than ARC and ZOO, but
it happens to be faster than ZIP.
Now, if the Sysop will be so kind as to allow me to upload it as
a self-extracting .COM archive (yes, it even makes
self-extracting archives WITHOUT external utilities, and the
whole program is a mere 20k in size!!!), I'll be happy to upload
it. I won't upload it as an .ARC, .ZIP, .ZOO or .PAK file,
though. In my opinion I think it deserves an exception.
Juan
Note: Juan is a Sysop on GEnie who is holding off switching to
ZIP for various reasons.

LHARC compresses tighter, but takes more time. Should keep PK
working hard.
