How can I transfer the contents of Local Folders in Thunderbird from one computer to another, if both computers are already running Thunderbird?

larrydparkerus

On my old (Win XP) computer I had saved hundreds of messages in Local Folders.

I got a new Windows 8.1 computer a few months ago. I installed Thunderbird and have been using it ever since. But I would like to copy the contents of the Local Folders from the old to the new computer.

Is there a way to transfer them on a memory stick and get them loaded into Thunderbird on the new computer?

You would have to close Thunderbird in the destination computer. You cannot edit or change profile files while the application is running.

I don't understand the answer. How can I transfer the messages to Thunderbird in the destination computer if the application is not running?
