Finding the last modified file through DOS command

Hello all,
I would like to know how to recieve the name of the file that was last modified through a DOS command. Let's say I have this case:
c:\folder\textfile-05.txt
c:\folder\textfile-12.txt
c:\folder\textfile-03.txt
c:\folder\textfile-43.txt

The number does not have anything to do with the modification date.
Anyway, let's say that in this example, the file at hand is 'textfile-03.txt'. What command do I write in order to get a result of 1 line i.e. 1 file that meats this criteria I am looking for...? The output should of course contain the file's name.
I would like to redirect the command's output to a file on the system. How do I do this, if the file&folder exists or not ...?

Thank-you.

Hi liorde,

Assuming that you are using WinNT/2K/XP, you can use this:
:: ----------EXAMPLE.BAT-----------
@ECHO OFF
FOR /F "DELIMS=" %%F IN ('DIR /B /A-D /OD /TW C:\FOLDER\textfile-??.txt') DO (
 SET FILE=%%F
)
ECHO Most recently modified file is:
ECHO %FILE%
ECHO %FILE% > X:\OutputPath\Results.txt
:: ----------EXAMPLE.BAT-----------

Hope this helps,

Hi,
Thank-you for the reply.
Is this solution not good for WinME/9x ?

Hi Liorde,

No. This answer will only work for WinNT/2K/XP.

This is because Win9x/ME does not have the "FOR /F" option which allows us to parse the output of a command.

Thank-you for the enhancement.
It was very important for me to know this.
Is there a solution that will work under Win9x/Me ...?

Thanks again.

Hi Liorde,

If you need this to work in Win9x, you should have a look here:
http://www.ericphelps.com/batch/samples/recent.txt

The relevent contents of that link are as follows:
------------------------------------
@echo off
dir /o-d /a-d *.* | find "-" | find ":" > en#er.bat
fc en#er.bat nul /lb1 /n |date|find " 1: " > en#er.bat
echo copy /y %%5.%%6 recent.txt > enter.bat
call en#er.bat
del en?er.bat>nul
cls
------------------------------------

This will copy the most recently modified file to "recent.txt".

It doesn't set the filename as a variable, but it's a decent starting point.

Hope this helps,
pb
