Код:

@echo off
set DIR=c:\TEMP

set "$F="& set "$1=%~n1"
SetLocal EnableDelayedExpansion
echo:!$1!|findstr/xrc:"[A-Za-z_-]*"|findstr/vrc:".............................................................">Nul&& set "$F=+"
EndLocal& set "$F=%$F%"

if defined $F (
  set "VAR=%~n1"
  call echo VAR=%%VAR%%
) else (
  copy "%~1" "%DIR%\"
  ren "%DIR%\%~nx1" "%~n1_%DATE:~-4%-%DATE:~3,2%-%DATE:~0,2%_%TIME:~0,2%-%TIME:~3,2%-%TIME:~6,2%%~x1"
)

P.S. для стандартной локали: DD.MM.YYYY HH:MM:SS

Еще вариант:

Код:

@echo off

setlocal enabledelayedexpansion

set "fn=%~n1"
set "tempdir=z:\tmp\"

if "%fn:~60,1%"=="" (echo=%fn%|findstr "[^A-Za-z_-]">nul||set "name=%~1")
if not defined name (
   for /f "skip=1 tokens=1 delims=." %%d in ('wmic os get localdatetime') do set "dt=%%d"
   set "name=%fn%_!dt:~0,4!-!dt:~4,2!-!dt:~6,2!_!dt:~8,2!-!dt:~10,2!-!dt:~12,2!%~x1"
   copy "%~1" "%tempdir%"
   ren "%tempdir%%~nx1" "%name%"
)
echo %name%
pause>nul
