Use xtool.exe test [file] to see which compression streams are inside the game files.
Razor12911 released several command-line tools that became industry standards: xtool library by razor12911 work

XTool solves this problem through . It scans target archives, unpacks those hidden internal streams back into raw data, and leaves instructions for rebuilding them later. This article provides an in-depth breakdown of how the xtool library by Razor12911 works, its underlying architecture, and why it is a critical utility for data optimization. The Core Concept: Precompression vs. Standard Compression This article provides an in-depth breakdown of how
: Reading the metadata map generated during Phase 1, XTool re-compresses the raw data streams using the exact parameters the game engine expects.
: XTool utilizes all available CPU threads for both encoding and decoding, making it much faster than older single-threaded tools like Precomp.
The entire philosophy behind XTool was born from a simple problem: . Razor12911 pointed out the bottleneck: "Games have become large in size in modern day, 60GB give or take and processing such large inputs takes a really long time because most of these precompression/preprocessing tools still use 1 thread even though systems these days rock 16 threads so why not make a tool that utilizes all of that raw power?"
