Downloading Scripts

Ok, I was at the blender website and I downloaded a bunch of scripts that I thought would really be a big help. So I extracted all of them and several of them came up with just a blend file. What do I do with these? And the ones that were .py files; I copied them into the scripts directory and go to the scripts window in blender and only 3 of them come up. There were more than 3 that I copied. Your help is appreciated.

If you reallly want help, you should give the name of the scripts that works or not.
