This has probably already been asked, but the syntax for even looking up the question is difficult to describe.
So, I have a directory of video files, some FLV, some MP4. I prefer the MP4 version IF the same filename does not exist as FLV.
So I want to delete/move/whatever any FLV file that already has an MP4 counterpart of the same filename.
Chances are, since I can't accurately describe what I want in English, writing it in CMD is not likely.
Thanks
