Drilling down into file structure searching for Thunderbird local folder

[zenzen]

Hi, welcome to the Zorin OS community!

You probably installed the Flatpak version of Thunderbird. Check for that with: flatpak list and see if Thunderbird appears in that list. If yes, you'll find the relevant files inside a .var directory.

See for reference:

Where is Thunderbird file in Zorin 17?

I recently upgraded to 17 and the technician said all of my files from the most previous version are still on my PC, but I can't find them. Where do I look to retrieve them? Thank you.
