trying to pass existing thunderbird data from old to new pc (win11 pro) - thunderbird last version 128.6.0.esr (32-bit) - our profile data ia over 30 GB - so we copied the whole directory as shown in the export funktion - after starting the import funktion on new pc it starts and ends after some seconds with error code :

Uncaught (in promise) NS_ERROR_FILE_NOT_FOUND: Component returned failure code: 0x80520012 (NS_ERROR_FILE_NOT_FOUND) [nsIFile.copyTo] 

   _recursivelyCopyMsgFolder resource:///modules/ThunderbirdProfileImporter.sys.mjs:652
   _importMailMessages resource:///modules/ThunderbirdProfileImporter.sys.mjs:581
   _importServersAndAccounts resource:///modules/ThunderbirdProfileImporter.sys.mjs:241

The tools>export menu pane warns not to do it for profiles greater than 2 gb. The safest way (all the time) is this approach:

Here is the link for moving a profile in Windows when installed in default location: 

https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer

here is the info in brief steps:

  1. ensure thunderbird is NOT running on old machine
  2. enter %appdata% in search window on task bar and press Enter key
  3. this should open windows file explorer in Appdata\roaming folder
  4. highlight the Thunderbird folder and copy to external media
  5. ensure thunderbird is installed on second computer and NOT running
  6. enter %appdata% in search window on task bar and press Enter key
  7. you should be in Appdata\roaming folder , copy&paste the exported Thunderbird folder there. This may prompt to overwrite an existing folder of same name. allow it
  8. start thunderbird and all should be there

The above assumes the profile is in the default location. Some changes are needed if profile is elsewhere.
