<div class="SECT1">
<h1 class="SECT1"><a id="EMACS-SAVING-FILES" name="EMACS-SAVING-FILES">17.5 Saving
Files</a></h1>

<p>In order to save a file, you type</p>

<table border="0" bgcolor="#E0E0E0" width="100%">
<tr>
<td>
<pre class="SCREEN">
<kbd class="USERINPUT">C-x C-s</kbd>
</pre>
</td>
</tr>
</table>

<p>Emacs will not ask you for a filename, the buffer will just be saved to the file it
was loaded from. If you want to save your text to another file, type</p>

<table border="0" bgcolor="#E0E0E0" width="100%">
<tr>
<td>
<pre class="SCREEN">
<kbd class="USERINPUT">C-x C-w</kbd>
</pre>
</td>
</tr>
</table>

<p>When you save the file for the first time in this session, Emacs will normally save
the old version of your file to a backup file, which has the same name appended with a
tilde: so if you're editing a file &#8220;<tt class="FILENAME">cars.txt</tt>&#8221;,
Emacs will create a backup &#8220;<tt class="FILENAME">cars.txt~</tt>&#8221;.</p>

<p>This backup file is a copy of the file that you opened. While you are working, Emacs
will also regularly create an auto-save copy of the work you are doing, to a file named
with hash signs: <tt class="FILENAME">#cars.txt#</tt>. This backup is deleted when you
save the file with C-x C-s.</p>

<p>When you are done editing a file, you can kill the buffer that holds it by typing</p>

<table border="0" bgcolor="#E0E0E0" width="100%">
<tr>
<td>
<pre class="SCREEN">
<kbd class="USERINPUT">C-x k</kbd>
</pre>
</td>
</tr>
</table>

<p>Emacs will then ask you which buffer you want to kill, with the current buffer as
default, which you can select by hitting <b class="KEYCAP">ENTER</b>. If you haven't
saved your file yet, Emacs will ask you if you really want to kill the buffer.</p>

<div class="SECT2">
<h2 class="SECT2"><a id="EMACS-QUITING" name="EMACS-QUITING">17.5.1 Quitting
Emacs</a></h2>

<p>When you are done with Emacs altogether, you can type</p>

<table border="0" bgcolor="#E0E0E0" width="100%">
<tr>
<td>
<pre class="SCREEN">
<kbd class="USERINPUT">C-x C-c</kbd>
</pre>
</td>
</tr>
</table>

<p>This quits Emacs. If you have any unsaved files, Emacs will tell you so, and ask if
you want to save them each in turn. If you answer no to any of these, Emacs will ask for
one final confirmation and then quit.</p>
