<descr>
<p>
The value in <var>CircularLinkDetection</var> is used, along with
FollowSymLink, in the Search method. They control whether a file is a symbol
link in a directory which has already been visited in the method.

When CircularLinkDetection and FollowSymLink are enabled, an internal hash of
processed directory names is maintained in the method. If a file is encountered
which resolves to one the already processed directories, it is not processed in
the Search method.

The default value for the CircularLinkDetection property is <b>False</b>, and
disables circular link detection.
