Restoring profile to new computer

more options

Hi, Just got computer back from shop where - rather than upgrade - they did a clean install of Win11. I was under the impression from them they'd backup everything on a new "backup" drive they installed to double my capacity as part of the upgrade process.

They're version of backing up Thunderbird left me with a folder "Thunderbird_profile_backup.zip" that is 9,698,657kb in size.

I am attempting to install Thunderbird on the essentially new computer and restore all data from the previous installation.

Is this even possible anymore at this point?

I have data in that file that is important not only financially but archived family info from now deceased members... I'd really like to recover it.

In short help! lol.

re: from Toad-Hall "Can you post images showing all the contents" First pic shows external drive housing backup from Win10 Thunderbird install with most recent extraction highlighted, 2nd shows content of that folder and what was copied per your instructions. 3rd shows where those contents were pasted... 4th shows "about:profiles" inside TB. When I followed instructions making "27dwqp1g.default-release" active none of the email accounts showed (again, I did follow all of your instructions: "Root directory...info..ends with 27dwqp1g.default-release Below it there are buttons - click on 'Set as default profile' Click on 'Launch Profile' = it opens in a new window. Close the original Thunderbird window.") When I switched back to the "Profiles\mhaohwku.MyProfile" email accts were back. Mark

I ran out of room but wanted to thank both you and David for all or your attempts in helping... I feel like I'm close to getting those files back and it's because of the 2 of you.

Sincerely, thank you!!

The contents of the '27dwqp1g.default-release' folder - It does not show all of the contents.

Locate the 'compatibility.ini' file - open it using Notepad and post image of contents. I presume you originally deleted this file and the current one is newly created.

In particular I wanted to see the 'prefs.js' files Some may have a number eg: 'prefs-5.js' Please post image showing all of them.

Posting screenshots since I don't know how else I'd get them to you... there's a total of 6 numbered prefs files will attach them plus one without a number. Looks like it'll take several messages to get them all posted. Here's the first
