data move profile import export

This article explains how to move Thunderbird data (such as account data and messages) to a new computer.

__TOC__ = Copying all your Thunderbird email data = You can copy your data by copying your Profile Folder and then telling Thunderbird where to find your Profile Folder. <br> #Find the existing name and location of your Profile Folder by selecting "Help > Troubleshooting Information" in the Thunderbird menu. Then look for "Profile Folder" and click on the Show Folder button. This will display the path of names starting with parent folders and ending with the name of your Profile Folder. #Use the facilities of your operating system to highlight and then copy this profile folder, with its contents, to a new location (with a new name, if you wish). Be sure you are not copying a profile folder while Thunderbird is running and using that folder. If you have a large amount of email data, the copying process may take a long time. #Tell Thunderbird where to find your Profile Folder, by using the Profile app. For example, in Windows 10, a) Close Thunderbird, b) Right-click the Start icon, c) Click Run, d) Enter this in the Open box (without the quote signs): "thunderbird.exe -p" , <br> e) Click OK #In the Profile app, create a new Thunderbird Profile for your new Profile Folder: a) Click the Create Profile button, b) Click Next, c) Enter a name for your new Thunderbird Profile (this does not need to be the same as the name of your Profile Folder), d) Click the Choose Folder button, e) Navigate to and select your new location's Profile Folder that was set up in Step 2, f) Click Select Folder, g) Click Finish <br> You will now see a Profile app window that displays your new profile in the list of your profiles. (You'll probably have at least one other profile, even if it's just called "default".) <br> If each time you start Thunderbird you want to select from a choice of profiles, uncheck the "Use the selected profile without asking ..." box. <br> To automatically use a specific profile, select that profile and check the "Use the selected profile without asking ..." box. (You can always start the Profile app again, to change this setting.) <br> <br> Close the Profile app by clicking the Exit button. <br> = Using Gmail to move messages = In this method, you transfer messages to a Gmail account and then synchronize them to your new Thunderbird installation. #Create a Gmail account if you don't already have one. #Create a Thunderbird [[Automatic Account Configuration|account]] on the original computer for your Gmail account. #Make sure that your Gmail account properties are configured to use IMAP rather than POP3. #In Thunderbird, create matching subfolders under your Gmail account for every message folder you want to move. Thunderbird will automatically create a corresponding folder in your Gmail account. You can create nested subfolders. For example... #;<br>[[Image:Thunderbird folders]] #For each folder you want to transfer, go to the original folder in Thunderbird, select all the messages, right-click and select {menu Copy To} and then select the corresponding folder in the Gmail account. As Thunderbird copies the messages to the new folder they are also copied to your online Gmail storage space. #On your new computer, install Thunderbird and create your Gmail account. #Your online folders and messages should now be available in Thunderbird on the new computer. As you click on each folder, it will synchronize with your Gmail account. =Your Thunderbird Profile Folder= The Profile Folder stores everything about your email, including locally stored messages and attachments, address lists, account settings, Thunderbird settings, stored passwords, tasks, calendar data, and data for add-on features. You can keep a Profile Folder on just about any kind of storage or device. Regularly back up your profile folder. Once you're sure you don't want the data in an old Profile Folder, use your operating system to delete it. Use good judgment about revealing your Thunderbird email Profile Folder names and locations to others.
