Moving your Mozilla Thunderbird information to another location on your computer or another device only requires a few steps.

Thunderbird stores your messages, settings, filters, address book, spam filter data, and more in your profile folder; the folder is in a separate location from the program files. This way, if you uninstall Thunderbird, your messages and settings will still be available, in case you change your mind and want to reinstall it. This is also useful if a program update fails. To find the name and location of your Thunderbird profile folder:

Start Mozilla Thunderbird.

Select Help > Troubleshooting Information from the menu bar.
