Does anyone know how i can load a quicktime movie file from a button that is within my flash movie?

I want the button to locate the quicktime movie file on my harddrive and then load it, so that it opens using quicktime.

Is there a line of code that loads external files? because i have tried LoadMovie, but it loads onto a level which is no good, and i have tried get URL but that is only for web use.

Any ideas?
