Copying a thunderbird program from an old computer to a new computer

I have followed your instructions at https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer and gotten nowhere all day. on it. You have "Profile Folders", a folder called "Profiles", a bunch of profiles (folders) inside the Profiles folder and profiles in Roaming and in Local paths. When I get the old profile 'k41******' copied to the new computer in both the Roaming folder and the Local folder the Thunderbird program still will not show me the old files. I don't need any of the thousands of emails in the old computer, just the Templates in one account. This should be easy. I should just copy the profile k41***** ect. and paste it into the "Profiles" (notice the pleural there) and then Thunderbird should work. But it does not.
