Winzip continues to get more creative with their tactics to get you to pay them money. Principally I don’t mind paying for software but Winzip just seems so, well, simple. The latest version of Winzip counts down the number of days it has been installed as well as the number of archives you have opened before it allows you to do anything. At 150 archives it finally pushed me to find a decent alternative. I’ve used 7-zip for the last three months and highly recommend it. It is fast, easy to install, and free.
