&gt; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &gt; Notice the 2nd line of code. This isn&#39;t legal. What is<br>
the cleanest way<br>
&gt; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &gt; to append an extension to a file path? I don&#39;t think<br>
/= will work; if I<br>
&gt; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &gt; remember correctly it will add &quot;/.txt&quot;.<br>
&gt;<br>
&gt;<br>
&gt; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; I think you basically have the option of doing:<br>
&gt;<br>
&gt; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 1)<br>
&gt; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; myPath = myPath.branch_path() / (myPath.leaf() +<br>
&quot;.txt&quot;);<br>
&gt;<br>
&gt; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 2)<br>
&gt; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; string tmp = p.leaf();<br>
&gt; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; p.remove_leaf();<br>
&gt; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; p /= tmp + &quot;.txt&quot;;<br>
&gt;<br>
&gt; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Both are not really pretty...<br>
&gt;<br>

&gt; &nbsp; &nbsp; &nbsp; I figured that would be the approach I would have to take. I&#39;m<br>
making best efforts<br>
&gt; to only append a filename when the extension is present, since as far<br>
as I can tell being preemptive like that is the cleanest solution.<br>
<br>
</div></div>Have you looked at ::boost::filesystem::change_extension???<br>
Somehow it is referred to as replace_extension in the docs, but this<br>
function will do what you are discussing I think.<br>
