You CAN use SetVol() with the working directory returned by SFGetFile().
I do this all the time, then use standard pascal reset() and rewrite()
procedures.  However, remember that this is only a working directory
and the system has a limit (40 I think) of them.  Using the working
directory number right after a call to SFGetFile() should be no
problem, but you may run into problems if you hold onto the WDRefNum
for a while (such as placing it into a queue) since the system may
clear a working directory on you.  If you need to make a working
directory permanent, call GetWDInfo() to get a dirID, then use the
HSetVol() procedure.
.
By the way, passing the working directory from SFGetFile() to SetVol()
is the primary way compatability was maintained from MFS to HFS.
.
At least that's the way I understand it ...
