Hey man, it was really dumb of me to post another version of ApocalypseColumns last night, seeing that you're the master and have already put all kinds of bells and whistles into your column script. That's what I get for doing computer stuff at midnight. 
But your features are terrific and today I added these ideas to RegexColumnsReloaded (three new properties: fileOnly, dirOnly, fullCupValue). Love it... Thank you so much.
PM is disabled but if you have other cool features you can think of for a column script parsing file names, I'd love to brainstorm with you, with a view of maintaining and improving that public script. You can reach me through the sites in my sig and I also started a thread in CoffeeShop to discuss file naming conventions.
Cheers!
