Reading External Files without Counter

Okay, so I was just wondering if there is a way to read the names of files from a directory in Actionscript 3 without the use of a counter (which would require the files to be numbered) and without another script such as XML or PHP. I’ve searched in the old posts and elsewhere, but I haven’t found anything. I’ve seen the FLfile API, but A. I’m not sure how to access it and B. I think it only does the whole URI where I would like a relative address. Any help, knowledge, or pages with clues to the answer would be amazing.
