OK, well, having to explicitly use 'sets\xxxxz-yy\' isn't really that much
of a handicap in the grand scheme of things. It would've just been a
bonus/freebie not to have to use it; but it's not a real problem, right?

Yeh, I agree -- there's a very good chance of that. It's typical for most
code that reads files to "just work" with subdirectories even if it wasn't
written with them in mind. (Writing files is a bit of a different story,
but usually only if missing directories have to be created on-the-fly.) As
long the filename buffer on the stack is, say, 64 or 80 or 128 characters or
more, then the program shouldn't crash from writing off the end of a string
if the length goes unchecked. And that's usually only an issue in low-level
languages like C, anyway. (James wrote LEdit in Turbo Pascal, right?
Pascal has string overflow checking built-in.)
