AFCP (AXS File Concatenation Protocol) is a metadata format for image files. Its main uses are embedding IPTC-IIM data, and thumbnail images. It's not clear what AXS refers to (since it was a business in Berkely, CA, US the initials may refer to "Alpha Chi Sigma", a university's fraternity).
It is designed to be used as a "trailer" that can be appended to a number of different file formats. It could potentially be used in other ways, and even has TIFF tag 34152 assigned to it. But it is not a self-contained format (it contains pointers relative to the beginning of the file), so such use would be problematic.
