Yep, you read that right! It seems that Adobe has released a free DNG codec 2.0 for Windows that essentially allows you to view your DNG files right in explorer as you wander around your hard drive. What a great little tool.
Adobe states “The DNG Codec provides a method for Windows 7 customers to browse and view DNG files and metadata information in Windows Explorer and open DNG files in the Windows Photo Viewer.”
