Use the PATH_PATTERN field to specify the path. You can use the same wildcard characters as with NAME_PATTERN.
For example, the following data type uses a criteria based on path.
DATA_ATTRIBUTES Project_Graphics { DESCRIPTION Graphics file for the QS project. Double-click the \ icon to see the graphic. ICON QSgraphics } DATA_CRITERIA Project_Graphics_Criteria { DATA_ATTRIBUTES_NAME Project_Graphics PATH_PATTERN */projects/QS/graphics/* }
