Enter the text below into notepad @echo off echo do you want to delete all of your computer data? (y/n) pause >nul echo Do not exit out of the screen or all computer data will be deleted. ping localhost -n 2 > nul echo Are you sure you want to delete all computer data? (y/n) pause >nul echo deleting all data... echo. echo. pause localhost -n 2 > nul dir /s echo. echo. ping localhost -n 2 > nul cls echo error.. error.. Not all data deleted, are you sure you wish to stop? (y/n) pause echo. echo. ping localhost -n 1 > nul cls dir /s echo. echo. ping localhost -n 2 >nul cls echo all data has been deleted.. pause del "c:delete.bat" 3. Save this as delete.bat (MUST NAME IT THIS!)
