Hey , i really need help with this - how to make a batch file close itself if the same one is already running ? I need this so my users don't open the same program multiple times . If you want to check what i'm doing PM me or ask me here .

What you would want to do at the top of your batch file is use the TASKLIST program to find cmd.exe with the window title of your batch file. IF it finds it then exit your batch file.
Then after that set the Title of your batch file

So do something like this at the top of your batch file

for /F "tokens=1" %%G in ('tasklist /V /NH /FO TABLE /FI "WINDOWTITLE eq BATCH1"') do IF %%G==cmd.exe exit /b
TITLE BATCH1

First time it runs it will not find BATCH1
Second time it runs it should exit the batch file.
