If you're performing this step on your own computer, plug a flash drive into your computer and select it as a save location before clicking Save. Doing so should open Command Prompt if your computer allows batch files to be run.  If you can't run the program on your school computer, plug your flash drive into the computer and then double-click the batch file.
