    You are appending the `x` as prefix to absolute path which makes no sense, You need to append `x` to `zxc` in the file path I guess, for that you must use `os.split()` to split the path and then select the last element, then modify it the way you want, and reconstruct the path using `os.join()` – ZdaR Feb 03 '17 at 08:17
  • *but i have errors* You should always include the error you are getting when you ask a question. – Grisha Levit Feb 03 '17 at 08:21

import shutil, datetime, os

x = v.strftime('%Y.%m.%d.')
file = "C:\\users\\v.korolev\\desktop\\dev\\python\\zxc.txt"
shutil.copyfile(file, "C:\\users\\v.korolev\\desktop\\dev\\python\\old\\%szxc.txt" % x)
