Sorry, I'm going to have to respectfully disagree with you on a few
things here George ...
Not all Mac files have resource forks. I can send you one without if
you like and you can verify it by trying to open it in ResEdit and
having it tell you that it doesn't have a resource fork and would you
like to create one.
Again, I believe the Finder attributes (dates, invisible flag, etc)
are actually part of the HFS and HFS+ definitions.
The DOS-formatted disk phenomenon you mention has to do with creating
the Finder.dat files which contain these attributes, but resource
forks are not created.
Also, a '/' is legal in a Mac file name. I think it's only the ':'
(the MacOS directory separator) that's illegal.
