Lesson 7: Creating Files and Folders

So far we only observed and moved. Now we create something new. `mkdir` makes an empty folder, and `touch` makes an empty file. Two simple commands that start building.

mkdir is building a new empty drawer. touch is putting a blank sheet of paper inside.

mkdir: A command that creates a new folder (make directory)
touch: A command that creates a new empty file
Empty file: A file that exists but has no content yet
