Windows Photos: It looks like we don’t support this file format

Windows Photos: “It looks like we don’t support this file format.”

The first thing you need to check is if other photo viewers can actually open the file. For example try the ‘old’ Windows Photo Viewer or a third party photo viewer. If those fail to open the photo as well, the file is probably corrupt. If the corruption is limited to the file’s header you may be able to repair it using the header of an intact file. I created a utility, JPG-Repair Toolkit, to help you do this for JPEG photos.

Also, if you are unable to open RAW photos (Cr2, NEF, ARW etc.) I also suggest to first try a RAW photo file viewer. If that fails to open the RAW photo too, you can try to extract a JPEG from it using JPG-Repair Toolkit.

Not repaired?

Not all files can be repaired. First requirement is that the file actually contains image (JPEG) data. You can watch the value for Entropy and the byte histogram if this is caused by an empty file (zeros) or a file filled with a byte pattern. These are the two most common issues causing a file to be beyond repair.

Healthy entropy and histogram

File filled with pattern(FF)

A zero filled file

Other format, only half byte values used

Other format, text file probably
