Thanks very much for your quick response.

For instance, if i have two subfolder in the INBOX. Is it possible that the
same UID of message appeared in both of the two folders.
In another word, the sequence number based on folder or mail account?

I wanna do some archiving operations on the filesystem level. So i have to
deal with the message files stored in the mailboxes.
