MUSE Book layout file (PCB)

I download the pcb file from here: 进迭时空开发者社区

However, I couldn’t open the file with any PCB viewer like Altium 365 viewer online or import it to KiCAD.

What software could I use to open/review the PCB file?
Is there any change to have a gerber file or any other format I could open/import with KiCAD or online viewer?

Thanks.

hi, josepablo!
the PCB layout files have been made in PADS. (.pcb file)
you can use PADS to open the PCB file or convert it to AD
