Is it worth clarifying that it is not the depth of the pathname per se,
but its physical length which causes problems.
i.e. $.a.b.c.d.e.f.g.h.i.j.file
maybe okay, whereas
$.a very very long folder name because my OS lets me do this.file
may not be.
(Though most buffers and suchlike will allow much longer paths than my
short examples.)
After all, one EW file here
(ADFS::HardDisc4.$.!Files.Files.TFT.Theatre.Shows.200712 _Aladdin.notes)
is more than the five levels deep and doesn't seem to cause problems.
