Please provide more information, including the OS. The normal location for profile is at c:\users\<yourid>\appdata\roaming\thunderbird

I am interested in this and also have a related question. TB is on my Windows 10 desktop PC, where I do most of my work and am constantly adding address book entries, filter and exception settings, etc. TB is also on my laptop.

Are there files I can copy from the desktop to update the laptop settings without moving all the email data as well?

And are they the same for 115 and 102?

I have had success by exiting Thunderbird and in Windows File Explorer, copying the abook.sqlite to another profile to replace its addressbook entries, and copying the msgfilters.dat file from within an account's folder to a profile with the same exact account.
