I mean that twins (RAW+JPG) and companions(XMP sidecar) must be linked in actions like, rename, move and delete.
Eg: If I delete the Jpeg, XnViewMP will delete the RAW and the XMP files too. Because actually if I delete the Jpeg or the RAW, the xmp sidecar remain as a ghost alone in the folder.

I think this option have to be in the Settings>General>File operations.
Thanks Pierre.
