Please add .nrw extension needs to be added to the x-dcraw virtual MIME type
Hi! I filled a bug in KDE thumbnailer for .nrw (Nikon RAW images) to be supported, they pointed me to this xdg package to request the file extension to be included.
Their suggestion was "The *.nrw extension needs to be added to the x-dcraw virtual MIME type in shared-mime-info."
