	 *          or a source file, this is the full path in the workspace to this resource. If the

	 *			 the first path is the full OS path to the archive (if it is an external archive),
	 *			 or the workspace relative <code>IPath</code> to the archive (if it is an internal archive),
	 * 		 the second path is the path to the resource inside the archive.
