Virtual folders play host to other folder types, including both concrete folder instances and subordinate virtual folders. You can build a (singly rooted) tree from a set of virtual and non- virtual folders, and treat them as though they were a combined or single entity. For example, listing the contents of such a tree is no different than listing the contents of a non-virtual tree - there's just potentially more nodes to traverse.
