My profile has multiple folders for each of my 6 mail accounts. E.g. for gmail: the ImapMail folder contains imap.gmail.com, imap.gmail-1.com, imap.gmail-2.com, imap.gmail-3.com, & imap.gmail-4.com. These folders are not the same & even have different years on the content file dates. Some contain only a few INBOX files, while others have hundreds of sequential INBOX-* files. Similarly, each of my other accounts have this same situation. Are these from multiple installations over the years? Is there a way to clean this up or to combine them into just 1 file without losing messages? I suspect I'm not really seeing any of the lower numbered ones, but only the most recent.
