>Yes - orphan. This reminds me of something I wrote for a client once. They wanted a button on a screen that would go out and delete all the orphan records. So I made the button and had the caption on the button... "Orphan Killer" ... which from a programming standpoint sounded kinda cool to me, however it horrified the poor little old lady in the office that had to run the screen. (ooops)
Yes, Orphan for a database POV but in this case, do we really call those physical files on disk orphan as well or there would be a better terminology.
As for the Orphan button you created, we'll have to mark that one among our funny messages. :)
