Not according to my experience and to Tech Note #80, which explicitly
states that CurDirStore "contains the dirID of the directory that SF
is displaying" and that "This information can be particularly useful
at hook time".  CurDirStore tracks directory changes during Standard
File.

Again, this contradicts both my experience and Tech Note #80.
