Coding & scripting forum: help modifying playlist script

Hi I came accrossa script that I will put below, It creates a playlist file for titles that are located in the folder that the batch file is run from, It would be great if someone could help me modify it so that it can be run from within a folder containing numerous sub folders and create a playlist file in each of the subfolders with the playlist file consisting of just the files in each subfolder.
thanks in advance.
