[Mediawiki-l] How do I .... link to "file://"

[Edmunds, Dave]

I'm trying to build a wiki application for internal use. I want build a
page with an external link to a file (ie a file:// not an http:// link).

I can't find a way to do that in MediaWiki? Is it possible? 
Is there some way to get MediaWiki to accept embedded HTML?
