Useless files

Where they are???My CoW is something 11 GB I want to decrease size.
So where are the useless files???

The major one is the pack folder in the CoW (1.5) directory. It won't be read by the game. My guess it's a left over from the time when the mod got installed into the mods\teutonic folder - that time it would read from the pack folder.
I still have to compare texture files in data\terrain but they don't really amount to much. Some folders that benefited from some footwork:
unit_info folder = 638Mb --> 139MB Here I simplified the matter by using the unified directory, seeing that the pics were identical for all factions
blockset\textures folder = 418MB --> 116MB This was achieved by using my "reduced settlement texture" mod for CoW 1.4.4
model_strat\texture = ??MB --> 90MB Simple resizing of textures

So far I am at an installed size of 9.59GB and I am wondering if I should\can remove the Russian voice.dat file (1.07GB)

Oki thanks waiting for some new news
