'''DIV''' files ('''DIV'''ision) are used in [[Mario Kart 7]] tracks to subdivide the course model in clipping bounding boxes, to reduce lag.

= File Format =
The file byte order is always little endian.

== Header ==
The file starts with a header that is 0x10 bytes long.

{| class="wikitable"
! Offset !! Type !! Description
|-
| 0x00 || Char[4] || '''File magic'''. Always ''BADC'' in ASCII.
|-
| 0x04 || UInt32 || '''File size''' in bytes.
|-
| 0x08 || UInt32 || '''[[#PAHS|PAHS]] offset'''. Always 0x10.
|-
| 0x0C || Int32 || {{Unknown-left|'''Unknown'''. Always 1000.}}
|}

== PAHS ==
The '''PAHS''' section ('''SHAP'''e) contains a group of [[#MRTS|streams]], one per polygon in the course [[BCRES]] file. The streams follow the same order as the polygons.

|-
| 0x04 || Int32 || '''Number of [[#MRTS|MRTS]] sections'''.
|}

== MRTS ==
The '''MRTS''' section ('''STR'''ea'''M''') contains axis-aligned bounding boxes (AABBs) that correspond to the polygon from the course model.
