Script to make a file inventory on a file server

Hello

To accomplish a company audit, I have to create a script that scan our windows 2003 standard file server and create a report with a list of certain files type like mp3, video and so on. In the list have to be present path, file name, and file owner. I already searched on Google, but I don't find anything usable.

Someone could help me ?

Thanks
