If I remember that thread correctly, the problem is that the folder ID's
are inconsistant, and so even w/o FileID support, there's a problem.
I think (I've not browsed that source recently) that the problem's that
the folder ID's are generated as the directories are walked.
I think one commercial package's solution was to just make an extra file
in the directory containing its folder id. Thus it'd be permanent.
Take care,
