Unpack .str from Godfather the Game (DATA packs not texts)

[Lefter7]

So, I'm using (or trying to use...) quickbms to export/decrypt ".str" files. I was able to change the text .str files easily with strtool (viewtopic.php?t=1840).
Till now i haven't found a way to unpack the files from .str, and that's because some .str contain more than one file, like textures, etc. The decompressed file has the coTS magic at the beginning. I'm going to attach some .str files, the small size ones that contain probably 1 file and the other ones that contain more than one.
Here are the str: https://mega.nz/#!M3JSkC6R!djhe9FEWrbpD ... yNfCqRF1bU
