How to copy emails from Thunderbird on Vista to Portable Apps?

Hi,

Im sorry if I asked this question again, but I look numerous of pages and I cant find the answer. And I desperately need help.

I am using vista and I follow the 'generic' guide by going to the documents & settings///xxx.default. THe problem is I only have xpc.mlf & xul.mlf to copy. So I am missing the rest of the files. But I can find them in Program File.

No matter what I do, I just cant get the portable TB to show my thousand of emails stored in my laptop TB. Please please help. I am so worn out.
