NOTE. For full decompressing StreamingAssets folder (3.4 gb >> 7.2 gb) set -c2mb

can you help explain it to me?

i am using Diskpan gui how to implement the method you gave?

or can you suggest me an article/video?

I don't understand please don't hate me

Hello everyone! I've tried to compress Cyberpunk 2077 v1.52 HotFix 2 using the following mask in UltraArc v2.9.0.0 R9:

MASK = srep+GLolz/$mscpack=msc+srep+GLolz/$anvilpack=xtool+srep+GLolz/$deflate=precomp+srep+GLolz

-) $anvilpack is for .archive files (i've used XTool_2020 v0.5.3 with Cyberpunk plugin);
-) $deflate=precomp+srep+GLolz is for .pdf, .png and .bin files (precomp version is 0.4.8).The command for precomp I've used is the following:

packcmd = "PRE\PRECOMP\precomp.exe" -d10 -cn -brute -o$$arcpackedfile$$.tmp $$arcdatafile$$.tmp

During decompression, when setup.exe tries to decompress "CP2020_Sourcebook_EN.pdf" file, an "Unarc.dll returned an error code: -1" error appears. If I try to decompress setup.bin file using a simple .bat file, there's no issue.
I don't think that .pdf file is corrupted (it's the second time I've tried to compress the videogame with a CLEAR installation, but the issue is the same). Where am I wrong? Thank for your answers!

use DiskSpan_GUI for Xtool

The problem is not XTool, because the error appears before the decompression of files compressed with XTool.

This error happens on a specific file? Maybe CLS settings are wrong.

Yes, the error appears always at a specific file. I use precomp to decompress .pdf files compressed with precomp.

I believe the method has been already posted for this game a while ago but here it is again as i havent tested it yet as im grabbing it right now.

Did you checked the cls.ini which the installer is using? Maybe there is the problem.

To be honest, I don't know which cls precomp settings are ok. I didn't use cls.ini for compression process, nor for decompression. What is strange is that decompression process decompresses some .pdf files, but suddenly gives -1 unarc error (always at same pdf file)

can anyone help explain when lolz, lzma, xtool and anything else in Diskpan Gui by Cesar82 is used?

Or can anyone suggest me something there to explain this?

Not entirely sure what you are asking.

Xtool = precompressor = responsible for decompressing/decrypting the input data. You need to select the correct codec for XTool in order for it to precompress successfully whether this be zlib, lz4 or an oodle library like kraken or mermaid. You can read more about XTool here.

LOLZ = the current best main compressor for game data like textures. LOLZ has support for header detection and raw file detection in order to gain best compression ratio. It's also slow, despite the fact it can be multithreaded. This is a closed source solution by ProFrager. You can learn more about LOLZ here.

LZMA = another type of file compressor, not as good as lolz in terms of compression ratio but immensely faster. Will produce larger output size. This algorithm is open source and built directly into FreeArc so you don't need any external compressors.

thank you
