Like I said, we need proper plugin for this. Just use mermaid+srep+lolz and go.

What about razor_mtx?

this is results of compressing *.pak, *.ucas, *.utoc files:
xtool:dd3:l10,d128mb - » Data-01.bin file size: 32.72 GB (00:49:44)
xtool:dd3+razor_mtx - » Data-01.bin file size: 32.63 GB (02:04:09)
xtool:dd3+lolz:dtb1:d256:mtt1:mt12:mc1023 - » Data-01.bin file size: 32.67 GB (06:23:46)

[KaktoR]

Then use razor_mtx if you like

hello
for StarWars Oulaws

for sdfdata from 34 to 46 :

xtool:c1792mb:mbk2:df20p+xtool:mkraken:core_2.9.5: dd3+LOLZ_NORMAL

for other sdfdata:

xtool:mmermaid:core_2.9.5:dd3+LOLZ_NORMAL

Other files:

xtool:dd3+razor_stdio

Also consider to extract wem and process them.

However I don't know why you split the files and let duplicates left behind.

I extracted bk2 files
I not yet found a way to extract wem files

[KaktoR]

I see. Tbf I looked on this game over a year ago, not remember anything.

I guess use mesa to extract wem files.

Carmageddon: Rogue Shift UE4Keys : 0x7A29E66C3CB184042A44F5E35EC023504940867C382D2E8E 1185E0F146D25B45 The key audit did not take place. How can I confused:mpress this game?

^
Seems to be just kraken streams, Use the Unreal plugin in xtool..
Should look like this:
xtool.exe precomp -mue5:k0x7A29E66C3CB184042A44F5E35EC023504940867C38 2D2E8E1185E0F146D25B45+kraken -c64mb -t100p -d1

 Compressing pakchunk9-Windows.pak
Compressed 1 file, 1,587,512,507 => 4,549,507,714 bytes. Ratio 286.58%
Compression time: cpu 2.83 sec/real 686.82 sec = 0%. Speed 2.31 mB/s
All OK

the vehicle I use DiskSpan_GUI V2 2.0.2.4 / I'm trying to do it, but it's not working—please help.

[Spinneret94]

^ I haven't touched diskspan for a while, but this should be the method ig:

 xtool:c32mb:d1:mue5,k0x7A29E66C3CB184042A44F5E35EC023504940867C382D2E8E1185E0F146D25B45:mkraken:core_2.9.10:lib_2+srep_new:392+LOLZ_NORMAL

It didn't work; I don't know why.

Could you use your own compression tool and share it with me for restoration?

[KaktoR]

Use ue4 instead.

 xtool:d1:mue4,k0x7A29E66C3CB184042A44F5E35EC023504940867C382D2E8E1185E0F146D25B45:mkraken:core_2.9.10:lib_2

If this does not work either send sample like this
Carma\Content\Paks\pakchunk16-Windows.pak

By KaktoR**, thank you for your help. My goal is to compress certain games whenever I feel like it, but sometimes I’m not sure how to do it or where to start.

Do you think this is the best option? Is it sufficient for ultra-compression, or is there a better alternative?
