Rename a file (or folder) by appending the current date and time to the existing filename:

  @ECHO off
  IF [%1] NEQ [] goto s_start

  Echo StampMe.cmd
  Echo Rename a file with the DATE/Time
  Echo Syntax
  Echo    STAMPME TestFile.txt
  Echo    STAMPME "Test File.txt"
  Echo    STAMPME "c:\docs\Test File.txt"
  Echo    Will rename the file in the format "Test File-2014-12-30@16-55-01.txt"
  Echo    In a batch file use CALL STAMPME ...
  GOTO :eof
  Set _file=%~n1%
  Set _pathname=%~f1%
  Set _ext=%~x1%
  :: Get the date/time
  FOR /f %%a in ('WMIC OS GET LocalDateTime ^| find "."') DO Set _DTS=%%a
  Set _datetime=%_DTS:~0,4%-%_DTS:~4,2%-%_DTS:~6,2%@%_DTS:~8,2%-%_DTS:~10,2%-%_DTS:~12,2%

  Echo   Year-MM-Day@HR-Min-Sec
  Echo   %_datetime%
  :: Rename the file
  REN "%_pathname%" "%_file%-%_datetime%%_ext%"

The last line of the batch file does the REName.


c:\> StampMe "sample file.txt"
c:\> StampMe "C:\logs\data\errorlog.txt"
c:\> StampMe "C:\docs\example folder"

An alternative 'quick and dirty' way to do the same thing in one line is shown below, this does work but is less robust as the results will vary according to regional/control panel settings.

c:\> REN "sample file.txt" "* %Date:/= % %Time::=.%.*"
