Open ff.files

Hello, I noticed that I cant open any Black Ops 2 fastfiles with FFViewer. I always get this error ( used file: common_zm.ff): "Error loading .FF: Bad state (incorrect header check)" . If I press the OK-button it says me that the file couldnt be opened because the file C:\...\common_zm-extract.dat couldnt be find. Maybe I asked a stupid question but it would be nice if someone could help me to see the files inside

Did you check which game FFViewer supports? I doubt it's all of them...

The reason why you can't open the .ff (FastFile) is due to the .ffviewer not programmed to open the Black Ops 2 .ff's. The only .ff tools that are publicly released are for the following Call of Duties,
1. Call of Duty 4: Modern Warfare
2. Call of Duty 5: World at War
3. Call of Duty 6: Modern Warfare 2
4. Call of Duty 7: Black Ops

respectz for the info

Well you know why its not working? Its a TAFF (Treyarc Fast File) so normal FF decoders do not work, this is to prevent cheaters.
