Importing local folders?

Is there a way I can import my local folders without restoring from a backup?

I have a copy of my data from appdata/roaming/emclient/localfolders

Can Import these easily without copying over the top? as this will overwrite what is already there.

I suppose you could export the emails you have currently in local folders in *.eml format, restore from backup and then import the *.eml files you saved before.

You may end up with duplicates but that can be sorted.
