[Users] archives as multiple files

[rikona]

I'd like to archive my emails in the form of single files as they are
stored by Claws mail. It seems to offer mbox saves, as a single file
of multiple emails, but not as a group of single files. Is there a way
to archive some, but not all, emails in an account as single files?

If it's not a program option, would it be possible to simply move a
number of the stored files to a different non-Claws directory without
fouling up the way Claws tracks each email message?
