The 23.2 GB I had in my old profile did update to the new profile on a new Windows 11 computer. I copied and pasted from Profile to Roaming. The copy and paste worked as described, but when I open Thunderbird it doesn't go to the update profile. I'm attaching a screen copy of my new Thunderbird app data. All the 4/24/2022 files were updated today, some marked "default" and some marked " default release. The file which has my big profile data from the old computer is: "euvmgbhx.default-release" 23.2 GB. I'm not a technical person, but have spent years restoring my Thunderbird profile data using the old procedures. Can anyone help?
