WinZip 14.0 Beta

WinZip is bar none, the most popular and useful file compression utility out there.

Alternatively you can download the latest stable version of this software.

WinZip is the original Windows Zip file utility. Combining power and flexibility with ease of use, WinZip appeals to the entire spectrum of data-compression users. First-time users are comfortable with the intuitive WinZip Wizard, while power users appreciate WinZip's seamless Windows Explorer interface and choose the award-winning WinZip Classic interface for their most sophisticated compression needs. In addition to basic zipping and unzipping, features include tight integration with Windows Explorer, support for most Internet file formats, advanced AES encryption, and much more.

What's New:

Microsoft Windows 7 is here, and WinZip 14 is ready for it. We’re taking advantage of Windows 7’s key features, and we’ve streamlined and improved many of our dialogs and operations to make WinZip easier to use and better than ever. We’ve enhanced security too, by automatically wiping any files that were temporarily extracted from your encrypted Zip files.
