a zip file is a compressed file. They compress it so it will download faster. What you need to do is extract the files. There are a variety of programs that will do this. Google search "Unzip" and a bunch of them will come up. Most of them offer a free version and all of them offer free trials, which will only work for a certain amount of time.
