You can find the correct driver for your graphic card here. In fact what you download is a compressed file. When you double click on the executable that you downloaded, the first thing it will do is extract the content of the package to the following location %systemdrive%\AMD so as you can see the unpacked folder with files is larger than the initial download. Afterwards the necessary drivers are executed automatically. You can verify it by yourself, just right click on the downloaded package and you will see the option to extract the content of the compressed file you have downloaded.
