Import from Directory for Version 7

My Windows 10 PC’s Hard Drive recenly Died. Although my EM Client Storage is on another Drive, I don’t know how to import data from this Folder back to a new installation of EM Client. I don’t have a Backup copy of my Emails. I tried Import from, then select EMClient6 but it only import email up to January. I guess that was the time I upgraded to EM Client7.
