What is an NRW file?

NRW files mostly belong to ViewNX by Nikon. NRW filename extension is associated with the RAW image format used to store high-resolution photographs captured with Coolpix digital cameras manufactured by Nikon. NRW images contain minimally compressed or uncompressed pixel data captured by the camera's image sensor. The camera used to capture the image does not apply any adjustments or corrections to the image before saving it. ViewNX, Photoshop, and PaintShop can be used to open and edit NRW images. Nero multimedia software suite uses a different NRW file format to save burning parameters and references to Windows Media Audio data used when burning audio compilations. NRW is also the filename extension of images captured by Nokia S40 phones such as the X2. When you capture an image on this phone, first, it saves it to a large (around 5MB) NRW file which is processed by the operating system before compressing the image to a smaller JPG file.

How to open NRW files

You need a suitable software like ViewNX to open an NRW file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your NRW file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a NRW file directly in the browser:. Just drag the file onto this browser window and drop it.
