Could you provide a few more details?  Are these local files?  How are the files named/organized?  What scraper are you using?  What exactly is the problem you're having?  The more details you can provide, the better.

Also, this thread will likely get moved to a more relevant sub-forum for the question.  It's not really a feature request.
