It's the nifs format and the only script available is this one: http://aluigi.org/bms/monster_hunter_nifs.bms The bad news is that it doesn't work at 100% on wecgame.ifs so it looks like I need to work on it. If it's not important I would prefer to not waste time on it because that format and script is quite complex
The problem is caused by a false positive at offset 0x79a781, because everything in this script is guessed. I have updated the script to version 0.1.2 where it's used the variable CHECK_WORKAROUND_SIZE to control this "check", in the previous version it was set to 0x10000 while now I have set it to 0x8000 that allows the script to work on your file. So problem partially solved.

I tried using this BMS script to extract these files but did not work. Not an important document, thank you.
