JXR Files? Safe To Open?

I have Windows 7. I open Windows Live Photo Gallery and I get a pop-up saying “Would you like to use Windows Live Photo Gallery to open these types of files? JXR” What are these files and is it safe to open? Thanks.


The JXR extension is a file developed by Microsoft for higher bit depth and higher compression without quality loss for professional photographers. This image file type isn’t popular due to the wide use of Adobe products by professional photographers, which do not natively export that file type.

The file format itself presents no risk to opening, but I’d recommend using a virus scanner program on any files you receive from the internet.  Image files have been known to include viruses. If you scan the file and it comes up clean, you should be OK with opening it in Windows Photo Gallery.
