Encode the magic in the names, by stealing a bit of the existing
filename space to encode it.

Such works pretty well as part of the magic to map long filenames
into DOS 8.3 names on my FAT partitions.

Apps linked with the appropriate Windows library see nice fancy
long names.

The rest of the world, including DOS apps and my Unix backup
scripts, see the primitive 8.3 names, including one or a few
extra files per directory, which are nothing special to them.

So long as these other apps don't presume to know that they can
keep some of the files in an apps directory, and drop others, then
it works well enough. And no self-respecting general purpose
backup program is going to presume such knowledge anyway.

I won't rest till it's the best ...
