I want to copy filters from one account to another, in particular to the main account.
I have some filters I imported from Eudora to Thunderbird. I want these filters to work on all accounts. I know that I can copy msgFilterRules.dat from one account to another, but there seems to be no entry in my profile folder for one account. It is my main account and was created when I imported from Eudora. There is a file named global-messages-db.sqlite which seems to contain many messages for the "missing" account, but there is no entry in the profile folder>Mail folder for that main account.

Is the main account an IMAP mail account? Then it will be under the 'IMAPMail' folder. Local folders and Pop mail accounts are under 'Mail' folder.
You can check where the main account is pointing to so to locate it.
Tools > Account Settings > Server Settings for the main account. look bottom right under 'Local directory'.
