Detect the compression methods of Repackers ?

And they won't tell you much about compression probably.

But you need to know, that Witcher 3 packages uses 4 types of compression algoes in their packs. And only common one is deflate. Everything else you have to find out. Maybe temp files will help you, maybe not

Regarding my bin's. Of course I use not only LZMA in FreeArc, but other compressors too. All public, though. I brute-force different types of data to find the best method. I keep all recordings of back-log archives, so when I see similar data, I already know what to use.

I use multicore decompression/compression, when it's possible and gives speed benefit (like Mad Max, where deflate compression is on minimal, 1 level).

Nothing special, leading Russian groups like RG Mechanics or RG Revenants do the same. Also groups (especially Revenants) have special tools and CLSs for compression/decompression Unreal packages or BINK videos. And of course they aren't public.

As opposed to your ideas, here we are in a public forum, where it is nice to provide their knowledge to those who thirst for learning, logically nothing obligatory.
This way you respond with the conviction that hardly anyone can understand the structure of compression and decompression of your work, do not think that benefits the guys here on the forum, in fact I think not really lead anywhere.

If I would be in boots of the person who asked, I would already understood, what files inside attached archive are doing. It's human-readable batches, for God sake.

Please don't expect from me real-life examples or compression strings for certain types of data. I'm not a teacher. If that's against the rules, I won't type anything else here, no prob.

For God's sake , you can write what you want here on the forum, and we do not expect any type of teaching from you, do not we need, but it would be nice to read from you, some interesting answers.

I can answer, but as I told above, the questions should be normal. You know what they say? Correct question contains half the answer. And that's true

One last thing i'll try to catch your method i'll try to restore the recently deleted files From the Drivers then i'll try the reverse engineering or i'll ask some of my friends who are expert in reverse engineering

For better challenge, ask your friend to revers-engeneer Revenant's BINK-decoder. My files rebuilder is so simple thing, it's faster to program it from the ground.

What`s with the Revenants BINK decoder, send me a link to the installation that uses it, and I could try to get you files that you want.
