Associations help Windows to know when to use WinZip® with your files. For example, because WinZip is associated with Zip files, Windows will always use WinZip to open Zip files. For best operation, WinZip should be associated with all types of archives that it supports.
Click Next to automatically associate WinZip with all supported archive types.
Click Associations if you would like to examine the associations that WinZip will create and specify which associations you want to enable.
