Streams that cannot be perfectly restored are handled using a patching engine (zstd or xdelta) to ensure data integrity.
:c - Codec(s) for precompression, multiple allowed: Preflate, Reflate, Zlib, LZ4, ZSTD, Kraken, LZO, PNG, brunsli, Flac, packjpg :b - Block Size in MB :t - Thread count
Instead of performing traditional compression, XTool decodes or "unwraps" streams of data that have already been compressed by standard game engines (like zlib, Oodle, or srep). This makes the raw data highly exposed, letting a heavy-duty compressor like 7-Zip or FreeArc achieve much better compression ratios later Xtool - Some tool repackers like to use - ENCODE.SU Forum . 🛠️ How Repackers Use XTool
Despite these limitations, XTool remains a foundational tool in the repacking ecosystem. Its source code is available for developers who wish to extend its capabilities or adapt it to new formats.
Excellent feature to reduce file sizes by eliminating redundant data.
One of the most critical, low-level utilities is the , created by the developer razor12911 .
Benchmarking data shared on performance forums like ENCODE.SU demonstrates XTool's efficiency. For example, when testing large asset archives like Grand Theft Auto V's x64w.rpf : Compression Method Final Compressed Size Real Processing Time (LZMA2 Ultra) Precomp v0.4.8 (Brute mode) 214.56 seconds XTool Precomp (-mzlib, 1 thread) 169.39 seconds XTool Precomp (-mzlib, 4 threads) ~586 MB 45.61 seconds
Use community repacks like razor12911’s only if you’re comfortable with potential warranty loss and recovery steps, verify the release integrity, and follow conservative testing and safety procedures.
The Razor12911/xtool GitHub project is continuously updated, showing its relevance in the scene. The tool has seen several improvements, including:
If a repack installation appears frozen while running an Xtool task, it is rarely broken. Decompressing heavily optimized structural data takes significant time. Hard drive speed (HDD vs. NVMe SSD) and thermal throttling are usually the determining factors for installation duration.
To give you a real-world idea of the xTool library’s power, consider a controlled test using a 40GB folder containing Unreal Engine 4 game assets (thousands of small .uasset files).

The process typically follows a three-step command-line workflow: Scan files to extract and decode hidden streams.
Unlike older precompression utilities (such as Precomp) that historically operated on single-core limitations, Xtool features advanced multi-threading capabilities. It scales efficiently across modern high-core processors, cutting processing times down significantly during both compression and decompression phases. Comprehensive Codec Support
: Because xTool is performing complex mathematical de-compression, it is normal to see high resource usage. If your installer hangs, ensure you have sufficient virtual memory (Pagefile) enabled.
