UnZip Description

Advertisement UnZip is a System Utilities software developed by Info-ZIP. After our trial and test, the software is proved to be official, secure and free. Here is the official description for UnZip: UnZip is an extraction utility for archives compressed in .zip format (also called "zipfiles"). Although highly compatible both with PKWARE's PKZIP and PKUNZIP utilities for MS-DOS and with Info-ZIP's own Zip program, our 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. A companion program, Zip, creates .zip archives; both programs are compatible with archives created by PKZIP and PKUNZIP for MS-DOS, but in many cases the program options or default behaviors differ. (For example, UnZip recreates the stored directory structure by default; PKUNZIP unpacks all files in the current directory by default.) New features in UnZip 6.0: - 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. - Fixed "Time of Creation/Time of Use" vulnerability when setting attributes of extracted files, for Unix and Unix-like ports. - Fixed memory leak when processing invalid deflated data. - Fixed long-standing bug in unshrink (partial_clear), added boundary checks against invalid compressed data. - and more
