Pedros, 51, is a former France international and said he was looking forward to taking on the country of his birth when the two teams face off in the last 16 in Adelaide.
"I am French but my heart is with Morocco," Pedros told reporters on Monday.
Six members of France's World Cup squad played under him at Lyon, including captain Wendie Renard and all-time top scorer Eugenie Le Sommer.
Pedros said after the Colombia game that he had the advantage of knowing the France team "perfectly".
Beating France, ranked fifth in the world, would be a remarkable achievement for 72nd-ranked Morocco.
