Do I still need Winzip if I have Windows XP? I thought I read something somewhere that said XP didn't require any additional software to unzip zip files....or was I dreaming? It hasn't worked yet without it, but I could have been doing any number of other things incorrectly. I have ZT 1 CC, and when I downloaded a file, it was there when I loaded ZT & went to 'check for updates' and 'check locally'. Then on the restart, of course, they weren't available in my zoo. I'm going to keep trying, because I know it said somewhere I have it-I remember something on the XP info said if you add another utility (and it named Winzip) it will replace the one that's already on there. I'm going to keep trying-wish me luck! If anyone knows how to do this, please help!
