I assume you are asking what is zip and what to do with it. I am going to assume you do have not read this
yet. You should do that first. Secondly, when dealing with a zip file you must have a program to extract it. I suggest Winrar
. Now onto your question. A zip file is basically like a package. Someone is giving their stuff away, they give one guy a keyboard(in this case, the file), and you a box with the computer, mouse and monitor in it(the zip). Essentially it is a way to package up multiple files. What you need to do then is extract the file using Winrar, once you have downloaded it. I also suggest going through and reading ZHDApps Tutorials
, they helped me out tons when I was figuring this all out.
