// components we get a directory of "" and a file of "". Opening a
// directory of "" works, because GetDirectoryForPath returns the
// root when there are no backslashes to split on. But inside the
// root there is no file named "". I don't see a better way of
// handling this, unless we create a "virtual" entry named "" in
// each directory that points to self? That seems worse, since
// we don't handle "." or ".." references either.
