WinZip is a trialware file archiver and compressor for Microsoft Windows, macOS, iOS and Android. It is developed by WinZip Computing (formerly Nico Mak Computing), which is owned by Alludo. The program can create archives in Zip file format, unpack some other archive file formats and it also has various tools for system integration.
History WinZip 1.0 was released in April 1991 as a graphical user interface (GUI) front-end for PKZIP. The ZIP file archive format (ZIP) was originally invented for MS-DOS in 1989 by Phil Katz.Computing Encyclopedia - Article about WinZip
WinZip 5.0 implemented built-in PKZIP routines and code from Info-Zip and so no longer needed the PKZIP executable.https://kb.winzip.com/130360/
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.
On May 2, 2006, WinZip Computing was acquired by Corel Corporation using the proceeds from its initial public offering.
