Adding files to an open Zip file (Zipping)

To zip files from within WinZip®, add them to an open Zip file. A Zip file is open if you created the Zip file or opened the Zip file using WinZip. To add files to the open Zip file, select files in the Files pane, then drag and drop them onto the Zip pane or add files by clicking on the Add icons on the toolbar and select a location or click on Add from My Mac or Add from Cloud from the Actions menu. The following sheet will display:
Add from My Mac

  1. Add Sheet: When the Add from My Mac icon or menu item is selected, the Add sheet slides down from the WinZip toolbar. You can then select files and folders to be added to the open Zip file. Once the selection has been made, click Zip to add the files to the Open Zip file
  2. File/Folder Selection: The upper half of the Add sheet contains the standard Mac Open dialog box fields allowing navigation through devices, places, and folders and the selection of files and folders.
  3. Add Options: The lower half of the Add sheet contains the Add option for encrypting the files being zipped, filtering what files are added and what method to use for adding file to the Zip. Check the Encrypt box and enter the password and re-enter the password for spelling verification. The encryption method used is based on the setting in the Preferences.
