LT3751 Demo Board Layout


I've acquired DC1322A Demo Board for LT3751 driver. To get a better insight into PCB design of my circuit I would like to get a better look how layout is done on the demo board.

I've been able to import and open the project from the product page:

in Altium Designer, but no trace of PCB file.

Could you please specify how can I obtain PCB layout file or at least open Gerber files in Altium?

Thanks in advance,
