As far as I understand, the separator is used in the context of IMAP 
only, and not the file system.

So a client using IMAP will open Folder1/subfolder or Folder1.subfolder 
depending on the separator.

Somebody can correct me if I'm wrong, but I don't believe it has an 
effect on the backend (besides disallowing the use of that character in 
a folder name).
