Server Utilities :: Export Only Procedures As Proc File

I have to copy all the procedures in database to local folder and extension( or file type) of each procedure is ".proc".

I did tried with dbms_metadata but as there are 300 procedures it consuming time & I want separate file for each one.

select
dbms_metadata.GET_DDL('PROCEDURE',u.object_name), u.object_name
from
user_objects u
where
object_type = 'PROCEDURE'
AND object_name in( 'P1');
