This is something in the ReadMe.txt of the Old "Commandos_3_Files.zip" File:
How to use:
To make the changes have effect you should extract the .zip file to the installation dir of the game.
Note that 86 files can't be decoded properly. They can be found in the folder "Decoding Impossible." I have the idea that
there are a few other .MAC files that arn't decoded properly too. I will check that later and update this file if needed.
When your mod is done you should post it at the Eidos forums, where you can find even more link to mods, tools and sites!!

I've decoded all of the files properly, guys can download to Mod the COMMANDOS3.

Something is moving, now that 86 files which can't be decoded properly are all had been decoded properly.
Of course a few other .MAC files are decoded properly too.

********All the files in this "Commandos_3_Files.rar" all get from  "DATA.PCK".

File's name:  Commandos_3_Files.rar
Download adress:  http://www.fs2you.com/en/files/9d7a8585-fe31-11dc-a62b-0014221f4662/

This is something about the old zip.

Just like these files:
The file in the zip which ones decrypted
Commandos_3_Files.zip---Decoding Impossible---Decoding Impossible---Data---ANIMS---DESNUDO.ANI

Open the "DESNUDO.ANI", you can see it's not decoded properly.

But in my Commandos_3_Files.rar , you can't see a file which is not decoded properly.
If you don't believe, you can have a try..... My English is not good, because I'm a Chinese people which not study hard, so maybe I can't SAY CLEAR.

Ok, I understand now, thank you.
