    The hierarchical access can not be mixed with a normal access. Thus when
    in a storage a stream with a path "a/b/c" is accessed using hierarchical
    access, another stream "a/b/d" can also be opened with hierarchical
    access ( if it is still not opened ), but the substorage "a" can not be
    opened ( it is locked by hierarchical access ).
