With the Redline release, all Crashday files and mods are now stored inside .cpk files. These files are just .zip archives and contain all of the game's content. If you go to the ...\Crashday\data folder you will find all of the game's .CPK content packages.

Do not edit the .cpk files inside ...\Crashday\data in any way. The game's anticheat will kick in and stop you from running the game if these files get tamperered with! If you want to change any content, create or use mods to do so.

.cdx files are encrypted packages and can not be opened.


Every .cpk in ...\Crashday\data contains a different type of content. This is what's inside:

data000.cpk

Common files

data001.cpk

Music files

data002.cpk

Ambience files

data003.cpk

Car files

data004.cpk

Vegetation files

data005.cpk

Dynamics files

data006.cpk

Tile files

data007a.cpk

English localization files

data007b.cpk

German localization files

data007c.cpk

Italian localization files

data007d.cpk

Russian localization files

data007e.cpk

Hungarian localization files

data007f.cpk

Turkish localization files

data007g.cpk

Portuguese localization files

Only one localization file should be present at a time, which one depending on your currently selected language for the game via Steam.


If you unpack all the .CPK files, you will get a folder named content. Its directory tree should look something like this.
