Is there a reason why file information fields are not available for the Find field when doing a rename operation? This functionality could be handy for a lot of situations. For example, right now I want to remove the parent folder's name from a bunch of files in multiple directories. Going into Flat View and doing a find on {parent1} and replacing it with nothing would be quite the time saver.
I think the main reason is no one ever thought of a reason for it before now, and the fields are usually used to add rather than remove thigns.
You could do that using a fairly simple rename script at the moment.
