I want to move Thunderbird local folders to an external drive (Seagate). I am working on a desktop computer with Windows 10. Where are the Thunderbird local folders? The files don't display anywhere in Windows explorer. I am able to transfer all other files such as jpg. and pdf. files from the desk top computer to the external drive by dragging and dropping, but I can't locate the Thunderbird local email files so as to be able to drag and drop.

Thank you for your help attempt. I do not find a mail folder within profile, within C drive. I have drive the path C: %USERPROFILE%; no mail folder there.

Start Thunderbird click help>moretroubleshootinginformation scroll down to 'profiles' click 'open folder' open Mail folder, then Local Folders and they should be there. Exit thunderbird before copying.

C:\Users\XXXX\AppData\Roaming\Thunderbird\Profiles

just change XXXX with your account
