Still very useful even if no longer updated. Do note that there might be safety/security issues, but when used in standalone setting I think it is nice to have available in your toolset.

(Info-)Zip 3.0 is a compression and file packaging utility. It is compatible with PKZIP 2.04g (Phil Katz ZIP) for MSDOS systems. There is a companion to zip called unzip. So far zip has been ported to a wide array of Unix and other mainframes, minis, and micros including VMS, OS/2, Minix, MSDOS, Windows, Atari, Amiga, BeOS and VM/CMS. Highly compatible with PKware's PKZIP and PKUNZIP utilities of MSDOS fame. Primary objective has been one of portability and other-than-MSDOS functionality. Features not found in the PKWare version include creation of zip files in a pipe or on a device; VMS, BeOS and OS/2 extended file attributes; conversion from Unix to MSDOS text file format; and, of course, the ability to run on most of your favorite operating systems.
  • Support archives greater than 2 GB and files in archives over the 2 GB previous limit (4 GB on some ports).
  • Initial Unicode support.
  • 16-bit OS support.
  • Supports standard zip encryption.
  • In addition to the standard store and deflate methods, Zip now can use the bzip2 compression format using the bzip2 library.
  • Included utilities: zipsplit, zipcloak, and zipnote should work with large files, but they currently do not handle split archives.
Supported hardware ranges 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.

Note November 2020: not possible to download Win32 binaries from the main source-forge website. https://sourceforge.net/p/infozip/bugs/62/

UnZip (Info-ZIP) v6.00

UnZip will list, test, or extract files from a ZIP archive, commonly found on MS-DOS systems. The default behavior (with no options) is to extract into the current directory (and subdirectories below it) all files from the specified ZIP archive. A companion program, zip, creates ZIP archives; both programs are compatible with archives created by PKWARE's PKZIP and PKUNZIP for MS-DOS, but in many cases the program options or default behaviors differ.

Included utilities: unzipsfx (self-extracting stub for prepending to ZIP archives), funzip (filter for extracting from a ZIP archive in a pipe), unzipsfx-gcc, and GUI modes (SFXWiz32, SFXWiz32-gcc)
