I&#x27;ve never experienced this in writing my own software. If I try to read or write to a directory I&#x27;m not allow to I simply get access denied.<p>f = open(&#x27;C:&#x2F;windows&#x2F;test.txt&#x27;)<p>try:<p><pre><code>    f.write(&#x27;test&#x27;)
 </code></pre>
except Exception as ex:<p><pre><code>    print ex
 
</code></pre>
IOError: [Errno 13] Permission denied: &#x27;C:&#x2F;windows&#x27;
