Hmmm..It worked, but not sure about the $2.99 message

Well, I read the other reviews and thought I’d give iZip a go. It installed fast from the App Store, I opened it and dropped the rar file on it. It un archived it, but a message said to fully unarchive it 2.99 needed to be paid. I don’t understand this message. I think the entire file unzipped. Ahhh….. after further inspection, it only gave me 16 items from the rear file. FREE - I think not. It works, but 2.99 will need to be paid. DDON’T ADVERTISE AS FREE. IT MAKES YOU LOOK CHEAP, AND AMATEUR-ISH.
