Want a carrier board pcb file suitable for Altium Designer

I want to redesign the carrier board, I have downloaded a .brd file is suitable for Allegro in the download center, but I use Altium Designer in most of the time, and I failed to translate .brd to .pcb, so I just want if there is possible to provide a .pcb file for me or how can I translate it? Thanks
