What files exactly? AE only opens its project files, all other files are imported as externally linked assets. Sounds like you do not understand these fundamentals and may really need to read up on the basics. If that's not it, then we really need much more info about what files you are trying to import, what version of AE you are using and all that other unimportant stuff....*lol*
yes indeed i was simply being stupit. lol
it is actuly very easy.
