We applied user feedback to help improve the Job Wizard, and added a number of compression and usability enhancements, as well as the ability to open .BZ2 and .RAR files. Like WinZip 10.0, you can select WinZip 11.0 with Standard or Pro features, and both offer compression enhancements that make WinZip 11.0 the most versatile WinZip ever. Our new "best compression" option allows you to let WinZip decide the best compression method for each file based on the file type. This will ensure that you maximize the compression of every file that you add to your Zip file. WinZip 11.0 also allows you to better zip .wav music files without compromising the integrity of the file or its sound quality. What's more, if you need to open a .BZ2 or .RAR file, WinZip can now be your tool of choice.

What's New in WinZip 11.2:
 
WinZip® 11.2 is an update to our most recent major release, WinZip 11.0. In addition to the features introduced in WinZip 11.1 and WinZip 11.0 (outlined below), WinZip 11.2 changes include:
* Unicode support to ensure international characters are displayed for filenames in a Zip file when the Zip file is shared between two computers having different code pages (the default set of text characters available for display.) For Unicode support, the Zip file must be created and opened with a zip utility that supports the Unicode extensions to the Zip file format such as WinZip 11.2
* Integrated support for LHA to create, open and extract LHA archives (.LHA and .LZH). This eliminates the need for a third-party DOS program
* Removal of support for DOS-based, third-party programs such as ARJ and ARC
* Minor bug fixes and enhancements
