to make a batch file (in other words a dos executable) open up notepad enter in a command that dos would recognise and save it with a .bat extension on the filename.
::script starts here
@echo off (this turns off the displaying of the commands when they are entered)
start (path) (filename and extension) and just do that for all the files u want to load and it will execute in that order but make sure to save it with the .bat extension.
