need macro to rename files (parts)

Hi. I have an aseembly (PCB) who has several dozens (even hundreds) components (parts). Those parts have names that could give to a third part (client) informations that we don't want to share. We'd like to rename all the components with a more generic name, like:

PROJECT #1.SLDPRT

PROJECT #2.SLDPRT

...

PROJECT #N.SLDPRT

Since I don't know anything about macros, could anyone help with that?

Thank you.
