I've been doing some modding and I have seen the file paths pointing to the art files(assets/art/units/…). When I try to find these files they are not there. I have looked in the standard directory and in the application package (control+click-Show package contents) and have been unable to find anything. Is it possible to access these files or are they buried somewhere impossible to find.

I have an /Applications/Civilization IV/Assets/ folder.

This folder contains /Art/, /Sounds/, /Python/, /XML/. It also contains four files called Assets0.fpk, Assets1.fpk, Assets2.fpk, Assets3.fpk

The majority of the game data is packed into the .fpk files.

My /Art/ folder does include /Units/ along with some other folders, and /Units/ has a few Units folders. However, these are presumably modified units, added by patches, that override or add to those in the .fpk files.

The .fpk files can be unpacked using a Windows application called PakBuild. I am not aware of a Mac equivalent to PakBuild, so as far as I know, the only way to expand these files on a Mac is via BootCamp, virtualisation (Parallels, VMWare), or using VirtualPC.

Thanks, too bad I can't access them

I think I have a basic utility working to extract the files on a Mac. I need to test it some more and make it more generally useful, but it seems to produce the same results as PakBuild. I'll get back in a day or so.

I have now posted a version 1.0 extractor for the AssetsX.fpk files. The thread with the download link is here (http://forums.civfanatics.com/showthread.php?p=6776526).
