Here's what Dired does:
* Displays files and directories in a tree-like structure. This allows you to easily navigate your file system.
* Provides commands to interact with files and directories. You can create, delete, rename, copy, move, and more.
* Integrates with other Emacs features. This makes it easy to edit files, search, and perform other tasks within Dired.
Why is it useful?
Dired is a popular tool for Emacs users because it offers a more efficient and flexible way to manage files than traditional graphical file managers. It lets you work with files in a terminal, which can be faster and more powerful than a graphical interface, especially for complex tasks.
In summary: Dired is a built-in file manager in Emacs that provides a powerful and efficient way to interact with files and directories.
