If He Is Asking That, It Is Possible If He Has A CFW, He Go Onto MultiMAN and Go Into The File Manager and Navigate To The GAMES Folder in dev_hdd0, Then Copy And Paste It On To His USB On MultiMAN, But If He Wants To Copy A Game From USB To PS3 I Think He Would Do The Same If He Had The Game Folder, example: [BLES01717-Call Of Duty Black Ops II]
