This is just a quick tip for Emacs beginners. I didn’t find these informations in one place, so it might be useful for somebody:
If not configured otherwise Emacs will create three different special files when editing a file:
Backup Files: The file name is appended with a tilde
Auto Save Files: The file name is prepended and appended with
Lock Files: The file name is prepended with
All files will are named similar to the files edited and placed in the same directory. I really dislike this default behaviour, because I don’t want any “magic” files appearing in my projects.
So here is the emacs config to deactivate each feature or to save the files in a different place:
(setq backup-directory-alist `((".*" . ,temporary-file-directory))) (setq auto-save-file-name-transforms `((".*" ,temporary-file-directory t))) (setq create-lockfiles nil)
