Using Game Saves

I am trying to use one of the Monster Hunter Freedom 2 game saves, but all the tutorials say to "extract" the folder. When I open/save the game save, when I right click it it just says open, or copy, or paste. There isn't an option to extract it.

How do I extract it?

You need WinRar.

What exactly is WinRAR, and how do I get it? =/

winrar is a program which compresses and extracts files similar to a zipped folder but better...ok to get it go here http://www.win-rar.com/download.html its only a trial version...or you can google another link if you want
