'''ANM''' files (likely short for '''Animation Folder''') use the structure of BUN files as well. With minimal metadata, {{unsure|the bundle archive was likely used to reduce load time by packing several files into one}}. The purpose they serve is different from the [[Pikmin Paired ARC+DIR Files|Paired ARC+DIR Files]], however, as all of the files within a bundle are unpacked into RAM as soon as they one is loaded, as shown by the [[OpenGl / Dolphin System]]. |

The bundle file is very simple. There is a header, followed by a repeating struct for every file contained within the BUN.

Similar to the [[Pikmin Paired ARC+DIR Files|Paired ARC+DIR Files]], the bundle archive emulates a folder path. When the file is unpacked in-game, it is assumed that whatever code is responsible treats the contents of the bundle files as if they were in the folder path described, starting from the root of the disc. | Similar to the [[Pikmin Paired ARC+DIR Files|Paired ARC+DIR Files]], the bundle archive emulates a folder path.
