No, and No.  There's no toolbox support for it, but the data is stored in
the File Type Descriptor Files in the *:Icons directory.  The format is
documented in Apple II File Type Note $42: File Type Descriptor Files.

I don't know, but I've seen this happen with my Show Clipboard NDA, too.
I have a bad feeling that the Desk Manager calls GrowWindow with
inappropriately-small MinHeight and MinWidth parameters when it gets
a mouse-down in your NDA's grow box.

It sounds like the Finder has set prefix 0 to the null string and set
prefix 8 to a string longer than 64 characters, and then you're using
an old-style Standard File call that is limited to 64-character pathnames.

A solution is to have your NDA use the new Standard File calls, like
SFGetFile2.

I don't think it has a well-defined use; the best approach is probably to
ignore it, and just use the backup bits on nondirectory files.
