In this video, we'll learn how to manage files and directories using Emacs Lisp. We'll also walk through a lot of real code examples showing how to use these functions in practice! By the end of the episode, we will complete the core functionality of the dotfiles management package we've been working on in this series called dotcrafter.el.
