Let's test it out by deleting our copied file. Then it asks if you're sure you want to delete it. Type Y and press enter to confirm the deletion. Now mycopy.txt is gone forever. Well, that is called a switch.
Most commands have certain switches that, when used, alter the way the command executes.
If you want to delete the directory we made in this tutorial, first change up to the desktop directory. You can't be in the directory you're going to delete. Now type del myfolder and press enter. If you left a file in the directory, it should alert that there are files in it.
