Razor12911 Xtool Precompression Tool

After recompressing chunks externally:

Commonly used workflows:

It "unpacks" these internal streams into a more compressible raw state, allowing final compressors (like LZMA2) to achieve significantly better ratios. razor12911 xtool precompression tool

Modern games rely on massive assets that are often already compressed using formats like Zlib, Oodle, or LZ4. Standard compression tools (like 7-Zip or WinRAR) often struggle to further shrink these files because they cannot "see" the raw data inside the existing compression. XTool solves this by:

recently added support for RAD Studio 12 , further improving scaling in multi-threaded environments.
