Have a look at
Observe that I have the WinF sources, sent me by Julian
Wilson when I wrote those notes.
He said they may be placed on the net somewhere. I could
now place them on my
page, because I have more available now.

I don't like it either, and
The (true) folding editor* is, I think, hugely underestimated
in its importance, and largely removes the temptation to try "managing
complexity" by spawning additional files. I have 3,000 lines in my
current project happily in a single file, and have in the past gone to 13,000.
I switched to a single-file style after TDS introduced me to folding c.
But I believe another factor gives rise to the many 'filelet' problem ?
the unnecessary factoring of code into a large number of very small routines,
each called just once. This seems to be endemic in programming texts,
regardless of language. Aside from sharing code, either within or
between programs, I never spawn a subroutine. Sadly, I was alone in this
position in my faculty. All the kids were led down the other path.
Readability (performance, and code-size) went down the plug-hole.
Java (and its ilk) encourage this IMHO, and extends it to classes.
Hoare argued that classes be used judiciously only as the top level of
abstraction. I found myself marking projects with code cast entirely as
a large number of very small classes comprising routines perhaps five lines
long ? introducing massive interconnection and thus almost totally unreadable.
Any algorithm was rendered all but indecipherable.
Perhaps I'm preaching to the converted ?
* by true folding, I mean that a fold is treated as a textual
composition, governing its contents ? i.e. indenting or (commenting
out) the fold indents (or comments out) each line of content. Few
so-called folding editors do this. (I use Michael
Haardt's fe though it fails this test, for want of one that
both passes and follows an emacs, rather than vi,
