Transferring Tbird to a ne PC:missing .js file in .default

I created an export .zip from Tbird on my current Win10 PC, intending to import it into a new Tbird installation on my new Win 11 PC. This is the second such migration: I did my own mailboxes no bother last night but this time its my wife's. My pack was less than 2GB, hers is just over.

I unzipped at the target PC, and attmpted the import. It failed with this error: Uncaught (in promise) DOMException: Could not open `C:\Users\marie\AppData\Roaming\Thunderbird\Profiles\39la2kp7.default\prefs.js': file does not exist (NS_ERROR_FILE_NOT_FOUND)

Is there any alternative to demanding even deeper pruning of her archived messages?

Chosen solution

Turns out to have been pilot error: I failed to notice that the <expletive deleted> thing was trying to import from \AppData\Roaming\Thunderbird\Profiles\39la2kp7.default\ instead of from the .default directory on the handover USB drive. The size of the zip file was a distracting and irrelevant red herring.

But why was it defaulting to AppData\Roaming\Thunderbird\Profiles\39la2kp7.default\ rather than asking? Why wouild the import folder be there? So noy just a pilot errror.
