R – How to make FlexBuilder recognize the MXML files as applications instead of components

I am attempting to import mxml files that I developed with Emacs into a new project in FlexBuilder…I have created a project and manually added all my MXML and actionscript files into FlexBuilder.

I now can't figure out how to run the application. I believe the problem lies in the fact that FlexBuilder believes that all my mxml files are components, when in fact, they are applications…Is there a way to change this?

When I right click on the file the "set as default application" and "run application" is disabled…

Thanks.
