Winzip 150

WinZip is a proprietary file archiver and compressor for Microsoft Windows and Mac OS X, developed by WinZip Computing (formerly Nico Mak Computing). It natively uses the PKZIP format but also has various levels of support for other archive formats.

WinZip has a 45-day free evaluation period, after which the program would still work even if the user had not registered, albeit with reduced functionality. However in later versions (14 and onwards) this feature appears to have been removed, although users are able to bypass this by downloading an earlier version.

History

WinZip 1.0 was released in April 1991 as a shareware Windows graphical user interface (GUI) front-end for PKZIP. Earlier in January 1991 Nico Mak Computing released a GUI front-end for OS/2 Presentation Manager called PMZIP. It used OS/2 versions of the PKWARE, Inc. PKZIP and PKUNZIP programs. Originally released on CompuServe, availability of WinZip expanded across major online services, including GEnie, Prodigy and other online services. In 1993, the WinZip announced the launch of its official support for customers on the Windows Utility Forum, serving over 100,000 members, updates and related information. The freely downloadable WinZip soon found itself included in best-selling Windows computing titles as part of companion disks, including the all-time best-selling Windows 3.0 book, Windows Secrets, by Brian Livingston. By 1994, WinZip became the official and required compression tool used by system operators on CompuServe for forum file libraries.

Starting from version 5.0 in 1993, the creators of WinZip incorporated compression code from the Info-ZIP project, thus eliminating the need for the PKZIP executable to be present.

From version 6.0 until version 9.0, registered users could download the newest versions of the software, enter their original registration information or install over the top of their existing registered version, and thereby obtain a free upgrade. This upgrade scheme was discontinued as of version 10.0. WinZip is available in standard and professional versions. However, the ability of Windows XP and later versions of Microsoft Windows to open and create .zip files (as "compressed folders") has reduced the need for extra compression software.

In May 2006, Corel Corporation, known for its WordPerfect and CorelDRAW product lines, announced that it has completed acquisition of WinZip Computing.

WinZip 1.0 for Mac OS X was released in November 2010. This version only works with Mac OS X Snow Leopard 10.6.
