Last time, I asked.  This time, I'll beg.  PLEASE PLEASE PLEEEEZE reply
if you have the answer.

You can't SetVol(...) to the working directory returned by SFGetFile
under HFS.  Even if you GetWDInfo and translate the wdRef into a volRef+
DirID, you can SetVol(...) to the volume (root directory) but not to
the DirID.

So how can you set the current default directory used by "Create", "Open",
and "OpenResFile" knowing only the SFReply.vRefnum?

Ideally, the technique should work transparently with non-HFS systems,
too (where it's trivial; you have no WDs).

THANK YOU THANK YOU THANK YOU Really, I mean it.
