Here’s some sample code for those trying out Adobe Apollo (Application wrapper for Adobe Flash and Javascript code) – a simple application to allow you to keep every nth file from an image sequence and creates a subdirectory where it renames the files and sequencially updates the names. It’s pretty fast considering it’s interpreted and the Async is good for not locking up the system.
Create a new Apollo application in Flex Bulder, and past in this code into your main.mxml.

I’m kind of happy that there’s some similarities to Visual Studio in Flex Builder — made the transition to it very comfortable.
