or you could just type the name of the exe then the file name followed by pause on the next line then save it as a batch file its what iv started doing for working with textures as after while you end up with to many files to be dragging files around
the cmd window will auto close after its finished the set task thats why you need pause on the last line
or just press the windows start button on your keyboard typ 'cmd' hit enter then that will open command prompt just drag your exe into ther hit enter it will tell you the command line arguments of that tool so you can check that your using them correctly
