Some | Some files within paks are compressed; in Prime 3, files are compressed with segmented LZO1X, just like Prime 2. In DKCR, on the other hand, files are compressed as a single zlib stream, like Prime 1. In either game, every compressed file is formatted the same way, starting with some metadata detailing the structure of the compressed data. | ||

== File Order == | |||
File order matters significantly and easily makes the difference between a pak loading quickly and optimally, or taking 30+ seconds on every door. While more research is required to figure out exactly how files should be ordered to optimize loading, the game generally clusters together resources that are used together, and a file's dependencies generally appear directly before the file itself. The game also often duplicates assets that are used multiple times within the same pak; there might be 10-11 copies of the same model file in order to allow the game to more easily find and load that file when it needs it. | |||
