Have you tried save as "myfile.launch" in your editor?
To add more depth on @ kscottz comment, you can find a nice tutorial about
roslaunchin the wiki. It is a video in which you can see how to generate and use launch files.thanks for support, I solve that
you can start from terminal:
touch mylaunchfile.launch and open it with vi mylaunchfile.launch then you can add the content you need
