Is the data in the big pak compressed beforr you use lolz?

It could be much easier to just extract all raw data and concatenate the data into two blocks.

Compress each block as required, then during unpacking stage, concatenate the two blocks and xdelta patch it to the original pak.

Hello yes I think about this but it's 30gb files
the xdelta file is big and patch is low speed

the pak is aes crypted.

What i've done:
take original pak and uncrypt it
extract "compressible" parts who lolz can have a raisonnable gain
extract low compression parts , compressed later with razor
extract small fast compression files (like txt, json, xml)
then pack each chunk block
(I've got a better compression ratio than compress extracted files)
during install => rebuild the big pak
recrypt pak
small hdiffz patch to recover a good crc
