UnZip 6.0

A basic archive extractor
UnZip is an extraction tool for archives compressed in .zip format. Although highly compatible both with PKWARE's PKZIP and PKUNZIP utilities for MS-DOS and with Info-ZIP's own Zip program, its primary objectives have been portability and non-MSDOS functionality.

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 zipfile.

What's New in This Release:
  • Support PKWARE ZIP64 extensions, allowing Zip archives and Zip archive entries larger than 4 GiBytes and more than 65536 entries within a single Zip archive. This support is currently only available for Unix, OpenVMS and Win32/Win64
  • Support for bzip2 compression method
  • Support for UTF-8 encoded entry names, both through PKWARE's "General Purpose Flags Bit 11" indicator and Info-ZIP's new "up" unicode path extra field. (Currently, on Windows the UTF-8 handling is limited to the character subset contained in the configured non-unicode "system code page".)
  • Added "wrong implementation used" warning to error messages of the MSDOS port when used under Win32, in an attempt to reduce false bug reports
