The files dir is not actually part of the website, it is below the website root. Anything below the html directory, the web browser will not be able to see (and for security reasons, you should not enable).
If you want to store files on your website for people to access, then create a directory called files or whatever in your html directory, and link to it with your index.html.
eg:
/home/e-smith/files/ibays/[[webpage]]/html/files
you can create this by ftping to the site.
