Moving Thunderbird Data to a New Computer

Backing up a profile

To back up your profile, first close Thunderbird if it is open and then copy the profile folder to another location.

1. Shut down Thunderbird.
2. Locate your profile folder, as explained above.
3. Go to one level above your profile's folder, i.e. to%APPDATA%\Mozilla\Thunderbird\Profiles\
4. Right-click on your profile folder (e.g. xxxxxxxx.default), and select Copy.
5. Right-click the backup location (e.g. a USB-stick or a blank CD-RW disc), and select Paste.

%APPDATA% is shorthand for the C:\Users\\AppData\Roaming\ folder, which depends on your Windows user account name.
