The original Maildir does not have any concept of folders. There are
some subdirectories where certain operations occur, but all
presentation to the user regarding folders in their IMAP MUA is
purely a representation built by the IMAP server on top of the flat
directory structure in Maildir.
With Maildir++, you actually get a direct one-to-one mapping of user
IMAP folders to subdirectories within the Maildir file structure.
This can avoid some of the problems with excessively flat directory
structures that start having serious performance problems once they
get more than a thousand or so files in them.
Of course, if the user doesn't creating any additional IMAP folders
within their MUA, then Maildir++ doesn't save you, whereas the
mailbox directory hashing and indexing scheme built into Cyrus would
never have those problems in the first place.
For Maildir versus Maildir++, see
<http://www.inter7.com/courierimap/README.maildirquota.html> and the
WikiPedia Maildir article at <http://en.wikipedia.org/wiki/Maildir>
for more info.
