Restore Local Files from Backup

I had messages from back in the 1980's saved in my Local messages folder (c:/users/paul/appdata/local/thunderbird/profiles/mt163uiu.defalut). Obviously, on a windows system. That system has crashed, I tried to reinstall the OS and that didn't solve the issue. It is either the SSD or power supply has died. Parts are on order.

But, because I reinstalled to OS I have a problem getting my old saved emails from Local back. I have a resent backup of the mt163uiu.default folder (actually everything in /appdata) but can't figure out how to import those files into a newly installed version of Thunderbird. To complicate matters a bit, the system I'm using is on Unbuntu. Thunderbird runs fine on it, but I'm unable to find a way to import the backed up c:/ ... mt163uiu.defalut folder.

Files like AWS 22MB and GitHub 3.2MB are mbox files. Copy an mbox file (ignore the .msf files) into Mail/Local Folders, from any backup or unused profile folder, subfolder of Mail or ImapMail, or any sbd (subdirectory) folder.

Just for clarity, under the mt163uiu.defalut folder I have two folders; cache2 and startupCache, and two files; _CACHE_CLEAN and .startup-incomplete.

cache2 seems to have most of the files; folder entries and index.

mt163uiu.defalut in appdata\ roaming will contain the profile data. The cache is stored in appdata\ local which it would appear you are looking at.

Mail is not stored in .../AppData/Local/... It is stored in .../AppData/Roaming/Thunderbird/Profiles/<xxxxxxxx.profilename>. If you've saved that folder, you can copy the mbox files, the large files with no extension in subfolders of Mail, Mail/Local Folders or ImapMail, to Mail/Local Folders in an active profile. When TB restarts, the folders should appear under Local Folders in the Folder Pane.

I think I'm getting closer. But for what ever reason I don't have any large files w/o extensions (actually any files w/o extensions) in ./AppData/Roaming/Thunderbird/Profiles/<xxxxxxxx.profilename>

However, what I did find was under: ./AppData/Roaming/Thunderbird/Profiles/<xxxxxxxx.profilename>/ImapMail/imap.gmail.com/Computer.sbd (plus several other folders with sbd extension)

Inside Computer.sbd I have: AWS 22.2 MB AWS.msf 62.1 kB GitHub 3.2 MB GitHub.msf 54.3 kB etc.

In addition to the <xxxxxxxx.profilename>/ImapMail/imap.gmail.com/ folder there are also these two branches with more large files and associated msf files; ./AppData/Roaming/Thunderbird/Profiles/<xxxxxxxx.profilename>/ImapMail/imap-mail.outlook.com/ ./AppData/Roaming/Thunderbird/Profiles/<xxxxxxxx.profilename>/ImapMail/imap-mail.outlook-1.com/
