Answer 1

This allows to rename the file with the creation date_time.

import os, datetime, time

folder = r"*:\***\***\TEST"

for file in os.listdir(folder):
    date = os.path.getmtime(os.path.join(folder, file))
    new_filename = datetime.datetime.fromtimestamp(date).strftime("%Y%m%d_%H%M%S.%f")[:-4]
    os.rename(os.path.join(folder, file), os.path.join(folder, new_filename + ".pdf"))
    print("Renamed " + file + " to " + new_filename)
    time.sleep(0.1)
