J2C, or "JPEG 2000 Codestream" files are portions of a JP2 (JPEG 2000) image returned as a codestream- i.e. they do not have the full JP2 image header but do have much of the same internal structure.

J2C isn't usually seen in the wild- often, you're taking part of a JP2 (the J2C) and immediately converting it into a plain JPG in software. The only tool I know of that reads them is called "KDU_SHOW" and is freeware off the internet.

Mime: image/j2c
