You only need VHosts, if you want to serv more then one site.
If you only want to change the location of your files from "C:/xampp/htdocs" to "C:/xampp/www/sa3bin" just change "DocumentRoot" and the related "Directory" directive in "httpd.conf".
(Or put your files in "C:/xampp/htdocs" without any changes...)
