-The '''CINF format''' is for skeletons. Skeletons are associated with models and skins through [[ANCS (File Format)|ANCS]] files.
+The '''CINF format''' is for character layouts (i.e. skeletons/armatures).

-The file starts with a list of all the bones in the skeleton. The first value is a 32-bit count, then the following structure loops.

+| ''Build Order ID Count''
+| '''Build Order ID Table'''
+| The first element of the ID table is the root bone, followed by the rest of the bone IDs in reverse numerical order. This table is enumerated in-order to construct a singly-linked hierarchy of bones using [[wikipedia:Left-child right-sibling binary tree|child/sibling convention]].

-Finally, the end of the file sets bone names. After the traditional count value, this short structure loops:
