THUG2 hidden folders?

[ATIMKOS]

So, I moved levels, movies, scripts and textures folders to new folder and game still work. How this is possible? Did game read files in this folders from other (hidden) folders?

Most of the game files are packed in prx files located in /Data/pre/.
The loose files are only used if the game fails to load it from the prx.

They are only included because the people who handled the pc port left them there for some reason.
