Maybe the following for decompressing:

Code: Select all

comtype dk2
get SIZE asize
get NAME basename
clog NAME 0 SIZE SIZE

and this one for compressing:

Code: Select all

comtype dk2_compress
get SIZE asize
get NAME filename
string NAME + ".big"
clog NAME 0 SIZE SIZE

And obviously the ea_big4.bms script for working on the decompressed file.

Aluigi thanks , works!
but
my problem now is when I extract 1 compressed big file from another Big file

example I have BIG4 file named '1.big', it contains another compressed big file named '2.big'

I extract 2.big from 1.big and I get decompressed 2.big:

quickbms.exe -o -d C:\ea_big4.bms then select 1.big
I get decompressed 2.big

now I want rebuild 1.big via
quickbms.exe -G -w -r C:\ea_big4.bms

I select 1.big in same folder where 2.big is placed, and here problem is old size < new size

Use reimport2 (-r -r instead of -r) if your new file is bigger.
The game may or may not accept the archive on which you used reimport2.
