Best Compression Methods for 'Specific' Games. Q&A

[wareck]

hello
I've got some question, its about "terminator dark fate"
the is a file called "basis.pak".
I'ts a PKZIP file (zip 2.0 with a password)
this file contains several files (animation,textures,sound ect)

In this file I extracted with sfk/partcopy a block from byte 882682388 to 4507627948.

I obtain a new file called sound.pak with is aroung 3.7Go.
it's again a PKZIP file with the same password of the big file...

I would like to know how to compress it , my first idea was to use xtool/flac or msc, but seems to not working (probably because password and packed)

I think the right way is to uncompress/decode compress then during installation use batch with sfk to re inject sound in basis.pak ...

thanks for your help
