Identification
CAT format is quirky, and potentially difficult to identify. It consists of a sequence of items, almost all of which contain an image. Each item seems to have a 373-byte fixed header, followed by variable-length segments. Provided the first item contains an image, a CAT file can probably be identified fairly reliably, particularly by testing the timestamp for the expected format. Also, bytes (hex) 28 00 00 00 (a BMP header field) should appear at offset {374 + {the 2-byte integer at offset 369}}.
