XnView Software

I would like to set XnView to display only files with the file extension *.ARW. Is this possible?

Thank you.

In the quick search bar at the top. just type .arw. Copy it so you can just paste it as you go from folder to folder
If you want the entire program to never show anything BUT .arw files, I would guess it could be done via Settings / Browser / File List / Custom Filters but I have never done much there. Take a screen shot before you mess with that too much

Thanks.
