I decided to get this app because it was Mac and PC compatible and the company is reputable. I finally swallowed the idea of paying $30 for an app when there are comparable ones for less than $10. I opened the software and was able to add my files relatively easily to a zip file. Unfortunately, when I went to password protect/encrypt the zip file, the option was nowhere to be found. After using the somewhat useless Help menu and Google searches, I finally found something that alluded to highlighting the files and then saving them to a zip in order to password encrypt them… and that did the trick. The option should be available from the WinZip menu. I’d like to see this in the next update.
