About Info-ZIP
Info-ZIP is a diverse, Internet-based workgroup of about 20 primary
authors and over one hundred beta-testers, formed in 1990 as a mailing
list hosted by Keith Petersen on the original SimTel site at the White
Sands Missile Range in New Mexico.
Info-ZIP's purpose is to provide free, portable, high-quality versions of the
Zip and UnZip
compressor-archiver utilities that are compatible with the DOS-based
PKZIP by PKWARE, Inc.
Info-ZIP supports hardware from microcomputers all the way up to Cray
supercomputers, running on almost all versions of Unix, VMS, OS/2,
Windows 9x/NT/etc. (a.k.a. Win32), Windows 3.x, Windows CE, MS-DOS, AmigaDOS,
Atari TOS, Acorn RISC OS, BeOS, Mac OS, SMS/QDOS, MVS and OS/390 OE, VM/CMS,
FlexOS, Tandem NSK and Human68K (Japanese). There is also some (old) support
for LynxOS, TOPS-20, AOS/VS and Novell NLMs. Shared libraries (DLLs) are
available for Unix, OS/2, Win32 and Win16, and graphical interfaces are
available for Win32, Win16, WinCE and Mac OS.
Info-ZIP code has been incorporated into a number of third-party products as
well, both commercial and freeware. Some of the more interesting ones (well,
historically speaking) include
the use of UnZip code in the unzip.dll
distributed with IBM's OS/2 Warp BonusPak and WebExplorer,
as part of the reinstallation code for the IBM Aptivas preloaded with OS/2
Warp, and as part of IBM's Infoprint product. Sun used Info-ZIP's
self-extractor to distribute the NT version of their HotJava browser,
Novell uses UnZip for NetWare 6 installation, and SAP includes it in
Business One.
Various Windows products such as WinZip
and the DynaZIP DLLs incorporate Info-ZIP code, too. And let us not
forget Pretty Good Privacy (PGP), an excellent encryption program that
uses Info-ZIP code as a first step in encrypting files. Info-ZIP's primary
compression engine has also been spun off into the free
zlib compression library, used in
Netscape/Mozilla/Firefox, the Linux kernel, Windows,
Java, virtually all PNG-supporting software, and countless other products.
Info-ZIP can be reached by a web-based form, but you'll have to read our
Frequently Asked Questions page to find out how.

hideous.

In addition, Info-ZIP would like to tip our collective hat to
Samuel H. Smith, the
gentleman who wrote the original MS-DOS unzip on which Info-ZIP's
UnZip 3.0 was based--and who kindly made the source code available
for free. Even though virtually all of his code has by now been rewritten
from scratch, Info-ZIP still owes Mr. Smith a debt of gratitude for getting
us into this mess. A package of virtual chocolate-chip cookies is in the
e-mail.
