def use_mult_process():
        from multiprocessing import Process

        ## byu_dir has not been declares
        files_list=os.listdir(os.path.join(str3, "010/"))
        process_list=[]
        for f in file_list:
            full_path=os.path.join(str3, "010/", f)
            if os.path.isfile(full_path):  ## not a dir
                ## send one file only to the function, and
                ## it is a file and not a dir
                q = Process(target=build_dict_json, args=(full_path,))
                q.start()
                process_list.append(q)

        for q in process_list:
            q.join()
