Vista Thunderbird backup help?

I'm trying (so far in vain) to locate my Thunderbird stored mail on a Vista machine, with the purpose of porting/syncing it with Portable Thunderbird on my flashdrive.

According to Thunderbird (the install on my laptop), my stored mail is in C:\[user]\AppData. Said folder does not exist on my HDD, or at least I can't find it. Any ideas where this folder may be on Vista?

I do have a Mail folder in Program Files, but that's from 2006 (wtf?).

The Thunderbird profile folder in Vista is located under the following branch...

AppData is the folder I can't find under User, searching on last date modified doesn't bring up the file itself.

(said computer's HDD is giving me the finger now so I can't do anything anyway)

ETA: Booting from a Knoppix LiveCD I can see that directory now. Weird.

You need to make sure the folder views is not set to hidden. Even searching for files. You need to set it up so that it can be seen.
