When the end-user runs the installer, the setup script calls the Xtool library to re-encode the raw data back into the exact compressed format the game engine expects. Basic Implementation and Command Usage
To understand XTool, one must understand the ecosystem it was built for: . When large PC games (often exceeding 100GB) are "repacked," their files are compressed to a fraction of their original size to make downloading easier. Standard compression tools like 7-Zip or WinRAR, while excellent for general use, are not optimized for the specific types of data structures found in modern video games (e.g., massive texture files, audio banks, and proprietary archives).

-t=8 : Allocates CPU execution threads (in this case, 8 threads) to speed up the scanning process. Restoring Data (Decoding) When the end-user runs the installer, the setup
The repacker runs a maximum-compression archiver over Xtool's output. Because the data is now raw and repetitive, the archiver finds massive optimization patterns. Standard compression tools like 7-Zip or WinRAR, while
Xtool features dedicated modules for handling diverse data streams, including zlib, lzma, lz4, zstd, and specialized game engine textures.
