Which form to file first dir 3c or dir 12

According to Section 152, Read with Rule 8 of ( Appointment & Qualifications of director rules), every Company shall file Form DIR-12 WITHIN 30 DAYS OF APPOINTMENT OF DIRECTOR AS PER SECTION 156 , EVERY DIRECTOR WITHIN 30 DAYS OF RECEIPT OF DIN SHALL INTIMATE THE DIN TO COMPANIES IN WHICH HE ACTS AS A DIRECTOR, AND AS PER SECTION 157, EVERY COMPANY WITHIN 15 DAYS OF RECEIPT OF INTIMATION UNDER SECTION 156, FILE FORM DIR 3C TO ROC . SO LOGICLLY DIR-12 SHALL BE FILED FIRST AS FORM DIR 3C WOULD REQUIRE MUCH MORE TIME LINE

Is it necessary to file both DIR -3C as well as DIR -12 because in DIR -12 all details of director along with his DIN no are already mentioned?
