Zipping Guide

To create a new Zip file, open WinZip in the WinZip Wizard mode. (If the WinZip Wizard does not open by default, just click the Wizard button in the toolbar.) You will be asked "What do you want to do?" Simply select "Create a new Zip file" and click Next. The WinZip Wizard will guide you through the entire process.

When you become more familiar with Zip file operations, you can also try the WinZip Classic interface. The Classic interface offers many advanced features that are not available in the WinZip Wizard.

Using the Classic interface, you can split large Zip files into smaller parts to overcome e-mail and other size limits; view, extract, and run individual files in a Zip file; remove files from an existing Zip file; encrypt your confidential files so that they can't be used without a password; and much more. To try the Classic interface, simply click the WinZip Classic button in the WinZip Wizard. Extensive program help is available for every aspect of WinZip Classic operation.
