Where are Google Docs stored?

[quietlybrilliant]

I'm trying to get Google Docs data off an old Android phone. I don't have access to the Google account for those docs anymore, but I can see the thumbnails in the app and assume the data is still on the phone. When I click the thumbnails it won't allow me to open my docs (because I don't have access to this old account anymore). But are the data stores somewhere on the phone? I'm trying to locate then with Android File Transfer but can't find them. Which folder would the Google Docs data be in? Thanks!
