How do I change a file extension file on Vista?

I know that I am supposed to press the layout button in Windows Explorer just left from the organize button but when I open up the explorer there is no Layout button, what should I do and/or how am I supposed to be able to change a file extension, please help.





Thanks in advance.|||I think this is how:


1. Open a folder or open Windows Explorer


2. Click the Layout button (to the left of the Views button) as shown in the picture below
