Well, that comment was not about DOS (but you are probably right).

I'm trying to set up a cc:Mail system, and those (DOS) programs
require SHARE.EXE, which they, according to what you seem to be
saying, should not need, as there can be only one of them on each
machine, since DOS is not multi-tasking.

I had the impression SHARE.EXE was for file locking on the common
shared file(s), which (I thought) can be one any type of disk
accessible to DOS at the time (ie FAT or Novell or maybe something
else).
