This reminds me that in the special readme for DJGPP's port of TeX, Eli
recommends checking config.sys to be sure that at least 50 files can be
open:

files=50

According to the MS-DOS 6.22 online help, valid values are between 8 and
255, with 8 as the not-so-generous default.

When I got started in 1989, 16-bit DOS programs were already requiring
settings like files=30, and it's no surprise that a 32-bit program (or set
of programs) as complex as TeX might want 50.

Maybe if a program really needs a large number of files open, it might be
prudent to include documentation emphasizing that point, as Eli did with
the TeX port.

Like you, I have no idea how this is handled in Windows.
