J6I is an image format associated with digital photos shot using Ricoh cameras. Ricoh represents a Japanese brand with a history of over 70 years, particularly known for producing printers, fax machines, digital and film cameras and other electronic products. J6I is a proprietary format for Ricoh cameras and might not be recognized by most regular image viewers, so it's probably best to convert it to JPG or PNG for better accessing and transferring options.
