so... i looked at this format in my way's and you told me this is a CPK file without header,
actually, this is not a cpk file, i've send you a tool, but this tool wants a license for startup.
file created with this tool. maybe i can do it by hex editor for .acb, but your awb_afs2.bms can't support files in reimport2, i think you should update this script for awb file (Just for support Bigger size)
This file (awb) has some offset in header, but i remember you solved same problem in other script. for example in mgs5_stpl.bms(Set old file as x\00 and set a new offset for reimported file, so script must be update to create a new offset)http://www.mediafire.com/file/b1cjzf5wn ... %20ADX.rar
