Actually no, it doesn't. So far as I can work out (they don't supply the
source code - can you believe it?) the indices are monlithic but each
message lives in a separate file in a rather complex tree (related to
the demented old Acorn file system restriction of 77 files per
directory, now laid to rest) denoted purely by a number I suspect plays
the role of an ID.
each index is stored in an eponymous file.
each message is stored in a separate file, named in some abstract manner
to make the indices as compact and easily parsable as possible.
subdirectories used at system's convenience to avoid excessively large
directories (Acorn can now handle 80,000 without much problem but
>200,00 is considered a bad move)
Just a thought.

Drugs may lead to nowhere, but at least it's the scenic route.
