WinZip, the original and most popular compression program for Windows, is a powerful and easy-to-use utility that quickly zips and unzips your files to conserve disk space and greatly reduce e-mail transmission time.
WinZip seamlessly integrates with Windows and provides AES encryption to keep your files secure. In addition to its award-winning Classic view, WinZip offers an intuitive Wizard for beginners to quickly and easily accomplish basic zipping and unzipping tasks.
WinZip supports two new compression methods (PPMd and bzip2) to allow you to compress your files even more, and the new Explorer-style view makes it much easier to navigate large, multi-folder archives. WinZip 11 is now available in Standard or Pro.
WinZip Pro offers the WinZip Job Wizard, which allows you to automate your repetitive zipping tasks, easily back up data sets, archive important documents, or distribute information to others. You can even move your valuable data off site by using the included FTP upload functionality, or you can burn your Zip file directly to CD or DVD.
