Where are my message filter definitions?

I lost all my message filters when I had to redo my Thunderbird connection to Yahoo (because they recently changed their security). I want to avoid this in the future, so I need to make sure I can back up my filter settings.

The filters are kept in "msgFilterRules.dat". That file doesn't seem to exist on my PC. I checked my account settings to see what Thunderbird has for "Local Directory". The entry is: "C:\Users\tiern\AppData\Roaming\Thunderbird\Profiles\mn5u78x1.default\ImapMail\imap.mail.yahoo-2.com". The folder "AppData" does not exist under "C:\Users\tiern".

Where are my filter definitions? Thunderbird version is 68.12.0.

appdata it's a hidden folder. You can see it if you select on windows explorer to show hidden files. Or you can open it if you click on start (windows stat menu) write run - open that run app and write on that small field: %appdata%

Or directly from Thunderbird - Help - Troubleshooting Information - on profile area click open folder
