FileNode nodes can be recognized because they have a NODE_TYPE system attribute with a 'file' value. It is recommended that you use the getNodeAttr() method (see 4.2.2) of tables.File class to get the NODE_TYPE attribute independently of the nature (group or leaf) of the node, so you do not need to care about.
