Driver file instalation

SO i was putting some new driverrs in my motherboard that I just installed and put the CD driver in of course, but I was wondering how I put drivers into files that the motherboard will use them I use chrome and I clcick on the driver I downloaded from the asus website and it comes up in a file that matches the version of the motherboard driver. Does that mean it will be used when it's in that file or is their a certain file I put it into?
