When I opened those 'encrypted' .DDS & .TGA files in the HxD HEX editor yesterday, I saw the BFC text on the very first line, it has become more clear what it is about right now. One of my buddies said that he saw the BFC writing too. I looked at these tools yesterday on this site, but I mustn't have paid much attention to the instructions below
Currently, I can decrypt encrypted .DDS & .TGA files by clicking on BFC1Extractor.exe as I want. With the help of TextureFinder.exe also, I place the necessary textures into the objects. There seems to be no issue, for now. Glad you answered, Blade
