Change Default Directory in SharePoint Designer 2007

Change Default Directory in SharePoint Designer 2007

Despite it being an older editor, I still use Microsoft's SharePoint
Designer 2007 for local development, I guess because I'm used to the
layout, color coding, and ease of use. I know there are other development
packages like Joomla! and Drupal, and I know there are lots of editors
that recognize PHP code and such, but I prefer SP Designer 2007 simply
because I've used it since it first came out and I like it. However, I
have never figured out how to change the default directory. Upon opening
the editor, the default folder it shows is located at
c:/users/owner/documents/my web sites/. How would I go about changing that
to a different path, like c:/webpages/?
Thanks, Harold
