How do I create a directory from within Emacs?

Question

How exactly can I create a new directory using Emacs? What commands do I use? (If possible, please provide an example)

Answer 1

I came across this question while searching for how to automatically create directories in Emacs. The best answer I found was in another thread from a few years later. The answer from Victor Deryagin was exactly what I was looking for. Adding that code to your .emacs will make Emacs prompt you to create the directory when you go to save the file.
