You obviously didn't see this bit

I'm sure he did - have you read the question you asked in your OP (my emphasis)?

but externals only works on files, not folders

So what is the problem you're having again ;-)

argh, i typo'd
i said it only works on files not folders, while it only works on folders not files and i showed an example of it working on folders not files, and asked how to make it work with files

so me and the RTFM person are both idiots. but the question is still not solved.
