First uses of kmail on new user

Hi

Created a new user and started kmail to set it up.
Its created the local folders as "/home/newuser/.local/share/
akonadi_maildir_resource_0/"  - how can i rename this safely to something more 
descriptive like "local-folders" - can i just rename it in dolphin and just 
update the kmail config accordingly?

regards

Ian
