I moved Thunderbird to a new PC recently. Thunderbird runs fine. I want to backup the profile folder. Windows file explorer does not see the profile ; yes I have set hidden files to view. The only profile it sees is the one I copied over from old PC that has not been modified (see image). In Thunderbird, I go to troubleshoot information, Profile folder, open folder, I get Location is not available error (see image). I go to about:profiles, open folder (any, see image), get same error. Profile manager does not see the old profile from old PC. How do I make Windows and Thunderbird see and open the profile folder Thunderbird is using successfully? Thank you

Did you install TB from the MS Store?

The problem is that the store version places the profile (I think) in a different location:

C:\Users\username\AppData\Local\Packages

but the about:profiles tab hasn't been updated to account for the change. I haven't used the store version, but if you can find it in Packages, you could move it to the standard location in .../Roaming/Thunderbird/Profiles, remove the store program, install the regular version, then make TB recognize the moved profile by creating a new profile in about:profiles and choosing the moved profile as the source of the 'new' profile. That way, the store profile could be managed from about:profiles.

You are a star! I did download from the MS store and Thunderbird does say its profile is at the expected C:/Users/username/AppData/Roaming/Thunderbird/Profiles/ but, it's in fact where you say. Problem solved, thank you very much. Clive
