Call of Duty Online *.ifs

[peterzhenhh]

Hi aluigi,
I found a tool named Wraith Cyborg to extract *.ifs files.But it has a bug. When two or more files have the same name in the same .ifs file , Wraith Cyborg will overwrite the previous.Unfortunately,I know little about C++,and DTZxPorter won't update it anymmore.

For example,there're 2 files named"UK_1_mp_pain.mp3" in "lf_init_common_mp_1_V29.ifs"

main/sound/voiceovers/codo_mp/tf/m1/UK_1_mp_pain.mp3
main/sound/voiceovers/codo_mp/tf/m2/UK_1_mp_pain.mp3

In the end,only 1 file was extracted.
IFS2.dll:https://www108.zippyshare.com/v/s7HnoN2G/file.html
"lf_init_common_mp_1_V29.ifs":https://www31.zippyshare.com/v/zRN3BsMp/file.html
Wraith Cyborg:https://www47.zippyshare.com/v/F4U9Cg4v/file.html

. Is there any way to extract them completely?

The format is a sort of new version of the "nifs" format used in Monster Hunter Online and for which I released an experimental script since the table with information is encrypted in such format.
But in this case I don't see readable data or compressed data (both zlib and deflate) or the "ASST" magic used in that other game and so on, maybe the files stored in the archive are encrypted or I don't know.
