-== Temporary Files ==
-Emacs creates two types of files for your benefit, automatically.
-=== Backup Files ===
-Backup files are created automatically whenever you save a file.  This enables you to easily go back to an older version if necessary.  The backup file is named the same as your original file but with a tilde (~) as a suffix.  If you're certain that you don't need the backup file it may safely be deleted (though it's probably better to simply ignore it).
-=== Auto-Save Files ===
-Emacs automatically saves your files periodically so in case of an unexpected event (e.g. emacs crashes) your file can still be recovered.  The auto-save file is named the same as your original file but with a leading and trailing number sign (#).  In the event of a crash, the file may be recovered by opening your original file and then executing {{SpecialKey|ALT|x}} '''recover-file'''.  Emacs will notify you if it detects a file in this state.  In general, emacs will automatically delete these files when it cleanly exits.
