How do you change a file name on Windows 7?

I've been trying to make a ringtone for my iPhone but when I click on Properties, Details, then scoll down to File, Name 01 Bad Boy m4a, I have to change (m4a) to (m4r) but it won't let me click on the file name and make the change.



Why won't it let me? Can someone please tell me how i'm able to make this change please?
