Created the below sub directory 0000 and moved all the 000-whatever directories to that directory, so I don’t have to wade through 155 directories, that I don’t currently know the purpose of. That way I start seeing the directories related to the course, beginning with 010-pkg-main-func-main. I also created a 0001-done sub-directory, to move the lesson completed directories to. So I can start out close to where I am in the course.
