That's not necessarily true. Some messages might only be stored in 
Akonadi's database, e.g. until recently moving multiple messages from an 
IMAP folder to a local maildir folder only wrote one of the moved 
messages to the physical location of the local maildir folder. (FWIW, 
copying multiple messages from IMAP to local works as expected.)

I encountered similar problems with moving/copying messages between 
different IMAP accounts.

Moreover, I think that some (probably dispensable) meta information 
about the messages (e.g. replied, forwarded) is only stored in Akonadi. 
At least, for some types of accounts, e.g. maildir.

Consequently, blindly purging all Akonadi data can result in data loss 
and is definitely not a recommended procedure for fixing problems with 
Akonadi.
