The basic unit of stored data in Unix is the file. To edit a file, you must tell Emacs to read the file into a buffer. This is called visiting the file. You can now edit the buffer and to save the changes you must write the buffer back to the file.
In addition to visiting and saving files, Emacs can delete, copy, rename, and append to files, and operate on file directories.
