The '''CINF format''' is for skeletons. Skeletons are associated with models and skins through [[ANCS (File Format)|ANCS]] files.

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.
{| class="wikitable"

| The first element of the ID array is the root bone, followed by the rest of the bone IDs in reverse numerical order.

After this is an array listing every bone ID in the skeleton. The first bone is the root bone, then the rest are listed in reverse numerical order.
{| class="wikitable"

| ''Linked Bone Count''
| '''Bone ID count''' (BC)
| '''Linked Bone ID Array'''
| This array includes both the parent bone ID as well as all children.

|-
| u32
| colspan=5 {{unknown|End of bone}}

| '''Bone ID array'''
|}
|}


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