I am running Windows 10 and am going to upgrade to Windows 11. To do this I need to save my Thunderbird system emails and folders, to enable me to reformat my disk drive. I can then fresh install Win 11 and Thunderbird to get my email working again. Advice as to what to save (profile?) in Thunderbird. Then putting this info into the new install of TB. Many thanks, Paul.

  1. ensure thunderbird is NOT running on old machine
  2. enter %appdata% in search window on task bar and press Enter key
