XnView - exclude NEF

[DenTNT]

Hello. I have a lot of photos from my Nikon camera and some photos are in NEF format. It is RAW-format, so it opens very long. I wish not to open it with xnview at all. How can I exclude it from showing in fullmode?

[xnview]

you have options>Filelist - custom files

Thank you. Its worked. But Is there correct description of the field?
"Please choose which files are shown in the browser"
Shown??? I think there should be "not shown".

The settings work both ways (include & exclude).
