Export Library – video_ts

Hi

I have some home movies from an old camera that are in Video_ts fomat but I have created nfo files for them so they are in my library.

I went export my library via the menu and selected separate files and overight old so that I could back up my watched a position staus.

But . . Its created new nfo files in the Video_ts foldet named video_ts.nfo this is not what I wanted.

I expected the nfo to override my nfo one folder up and to have used the name I have given the home movie

What have I got set incorrectly ?
