Emacs: Don't create #these# files when not saving modified buffer

Question

How do I prevent Emacs from creating backup copies of buffers I don't wish to save when I kill buffers that have not been saved?

Accepted Answer

See Here

Short version: put

```
(setq make-backup-files nil)
```

in you .emacs file, or toggle this feature at any time with `M-x auto-save-mode`.

Here is the Emacs Manual Node.
