How do I insert my filename in the footer or on the master slide?

I need to insert the filename on the bottom of every slide, can this be done?

You have to use code for this.

Thanks, works fine, but not quite what I need -- let me try this -- can I
insert a text box on the master, as well as a button, and click the button to
insert the filename? That way I can place it wherever needed, and not
interrupt my footer, which is a needed confidentiality clause.
