PLEASE NOTE – thanks for your interest in the Raw Image Extension (Beta). It is currently in development for a future version of Windows and requires Windows Insider build 18323 or later.
The Raw Image Extension adds native viewing support for images captured in raw file formats produced by many mid- to high-end digital cameras. By installing the package, you will be able to view thumbnails and metadata of supported raw file formats right in Windows File Explorer or view images in the Photos app. The current version of the extension supports a long list of cameras, however some Raw formats like .CR3, and .GPR are not currently supported at this time.
This package is made possible thanks to libraw open source project (http://www.libraw.org). Check out https://www.libraw.org/supported-cameras for a list of supported cameras. Libraw library is licensed under COMMON DEVELOPMENT AND DISTRIBUTION LICENSE Version 1.0 (CDDL-1.0).
(Please forgive me if I should not be posting this here, but I figured as LibRaw is open source it was relevant news)
