Holy cow, it worked! My little script automatically found files that were older than 7 days and asked me if I wanted to delete them!

I also deleted about a hundred old, unused media center personal copies. It was a drag until I make a macro that did all the button-pushing for me. Now all I have to do is bring up the bib record, hit a shortcut key, and, bickety bam, it deletes the item, holding, and bib records automatically.
