UnZip
UnZip will list, test, or extract files from a ZIP archive, commonly found on DOS and Windows systems. A companion program, Zip, creates ZIP archives; both are part of the Info-ZIP project. Both programs are compatible with archives created by PKWARE's PKZIP or Nico Mak's WinZip, but in many cases the program options or default behaviors differ.

Recent releases
- 11 Mar 2005 13:02
Changes: This is a maintenance release that adds support for the VCEmbedded 3.0 WinCE compiler and fixes various minor bugs (none security-related).
- 23 May 2004 20:02
Changes: This is primarily a security-fix release, correcting a textmode data-corruption bug in 16-bit ports and several directory-traversal flaws (involving invalid filename characters, quoted characters, symlink traversal, and local/central-directory filename mismatches). It also adds support for restoring directory timestamps under Windows.
- 08 Jun 2002 13:03
Changes: Support for PKWARE's Deflate64 compression method, support for simple "execute command after extraction" in UnZipSFX (compile sources with CHEAP_SFX_AUTORUN defined), and a fix for a directory-traversal security hole with a new "-:" option to override.
- 21 Aug 2001 18:04
Changes: This release removes unreduce.c (now available only as a separate add-on archive) and the Amiga timelib code to eliminate final distribution restrictions beyond the BSD-like Info-ZIP license. There is a generic replacement for the timelib code. Filename mapping of Unix ``dot'' files to DOS 8.3 format has been improved.
- 30 Jan 2001 06:14
Changes: A switch to Info-ZIP's new, BSD-like license (under which Zip 2.3 was previously released), decryption source code, a new Novell Netware port, and a new web site (the old one still exists, but is unable to redirect to it).

That is incorrect. The zlib in-memory, deflate/inflate compression library is there (or at www.zlib.org/), but Zip and UnZip are separate (and older) command-line utilities for processing zipfiles. They live at www.info-zip.org/pub/i...
(web pages) and ftp://ftp.info-zip.org/pub/infozip/ (files).
Note that UnZip can use zlib, but this is optional.
