I had a near complete computer disaster [ power supply sent high voltage almost everywhere]. I have a new computer now, and have installed Thunderbird. I was able to capture most of the data from my old C drive, including the data in "user". Immediately upon completing the setup of the new Thunderbird, it downloaded all the emails on the server. now I have thousands of emails from my "old" Thunderbird [which I must save], as well as a new group just downloaded. Can someone tell me how to combine the old emails into the new ones just downloaded? thank you MOST kindly for someone able to assist me. Regards, George [email removed from public]
