RAR archive of about 875 KB labelled as mainboard material for an ESC model P23G; the name does not say whether it holds a schematic, boardview or firmware, so check the contents first. ESC here most likely refers to the board maker ECS, but that is not confirmed by the name. Files of this kind are used to trace power rails, locate components and test points, or reflash the BIOS chip. Compare the model and revision printed on the PCB with what is inside before acting on it.
