They are all divided into subfolders by time period. I'm not worried about Gmail because I can get them from the server again - but my archived work emails are already removed from the server so i need them to be secure. Size of my fresh identity size is around 8GB which is pretty big and I note your warning that my identity could get corrupted again. I have two accts: one Gmail and the other exchange (work). I have also followed your advise to clean up all the junk on my Gmail server and now ready to re-download my much reduced email to my new identity. Relatively smooth though I lost a chunk of data from my gmail which was ok because I didn't delete them from the server so I could re-download. Took 3 days of rebuild attempts and finally settled on the export using First, you're awesome and thank you! Have been following your instructions on OfficeforMacHelp to move my Exchange messages to my Outlook for Mac 2011, after upgrading to El Capitan.
