The camera will not recognize changes made to image files (including numbering) not made in the camera.

Again, the camera will only recognize image file numbers created in the camera. When you modified the file names, the camera lost the ability to read them.

That is what I would expect the camera to do in that situation. In other words: the camera is working as it was designed to. Now that you have File Number Sequence set to ON, the camera will continue to number the image files sequentially until it reaches DSC_9999, then it will create a new folder and reset to DSC_0001 again.

The camera is not easily fooled.
>Any idea regarding that issue ? Am I doomed ?
No!!! The camera is working normally. Good Luck and Enjoy your Nikons!
