Rename a file (or folder) by appending the current date and time to the existing filename:
@ECHO off
SETLOCAL
IF [%1] NEQ [] goto s_start
Echo StampMe.cmd
Echo Rename a file with the DATE/Time
Echo:
Echo Syntax
Echo STAMPME TestFile.txt
Echo:
Echo STAMPME "Test File.txt"
Echo:
Echo STAMPME "c:\docs\Test File.txt"
Echo:
Echo Will rename the file in the format "Test File-2014-12-30@16-55-01.txt"
Echo:
Echo In a batch file use CALL STAMPME ...
GOTO :eof
:s_start
Set _file=%~n1%
Set _pathname=%~f1%
Set _ext=%~x1%
:: force an error using robocopy that will give us the current date
For /f "tokens=1-6 delims=/: " %%a in ('robocopy "|" . /njh ^| find ":"') do (
set "_YYYY=%%a" & set "_month=%%b" & set "_day=%%c"
set "_hour=%%d" & set "_min=%%e" & set "_sec=%%f"
)
Echo %_YYYY%-%_month%-%_day%@%_hour%:%_min%:%_sec%
:: Save the date/time in ISO 8601 format:
Set _datetimestamp=%_YYYY%-%_month%-%_day%@%_hour%-%_min%-%_sec%
:: Rename the file
REN "%_pathname%" "%_file%-%_datetimestamp%%_ext%"
The last line of the batch file does the REName. Based on the lengthy forum threads here and here.
If you save this as a batch script (stampme.cmd) on the desktop, you can drag and drop any file, from a local drive or UNC path, and drop it onto the icon - that will rename the file without moving it from the original location.
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::=.%.*"
