Xtool Library By Razor12911 -

| Algorithm | Use Case | Notes | |-----------|----------|-------| | | High compression ratio | Standard in many repacks | | Zstandard (Zstd) | Fast decompression | Great for modern hardware | | Brotli | Web/content compression | High ratio, slower | | Deflate | Compatibility | Legacy support | | PPmd | Text/log compression | Good for repetitive data |

: While it is widely considered safe when sourced from reputable repack sites, some antivirus software may flag it as a "false positive" because it behaves like a system utility that modifies files (it is decompressing data).

The Xtool library is a highly specialized data pre-processing and compression utility designed to decode, transform, and optimize streams of data before they are fed into standard compression algorithms. Xtool Library By Razor12911

| Feature | Description | | :--- | :--- | | | Full support for all codecs during both encoding and decoding to maximize speed on multi-core CPUs. | | Stream Deduplication | Removes duplicated data streams to improve decoding times, lower memory usage, and improve compression ratios. It functions similarly to tools like SREP but operates before them for better efficiency. | | Codec Support | Natively supports codecs common in games, such as zlib, lz4, zstd, and the Oodle suite (Kraken, Mermaid, etc.) . It can also decompress these streams, expanding them to a raw state for better re-compression. | | Database Generation | Can create a database (.xtl file) that maps out a game's file structure, serving as a plugin for faster processing of that specific game in the future. | | Stream Depth & Patching | Can scan for data streams nested within other streams for maximum compression. Streams that cannot be perfectly restored are losslessly patched using xdelta. | | Flexible I/O | Supports stdin/stdout, allowing it to be seamlessly integrated as a plugin or external codec for other tools. It can also accept an entire directory as input. |

Razor12911 designed Xtool to utilize modern multi-core processors. By splitting data streams across multiple CPU threads, Xtool drastically reduces both the time it takes to create a compressed archive and the time an end-user spends installing it. 4. Seamless Integration | Algorithm | Use Case | Notes |

Commands allow repackers to set strict memory allocations ( --mem=# ), optimizing performance across both low-end setups and high-end rigs. Xtool Performance Benchmarks

) often contain already-compressed data streams that do not compress further with standard tools. XTool "unwraps" these streams, making the data "raw" and more compressible for final archiving. Performance:

The is an open-source command-line tool and data-processing library designed primarily for game repackers to maximize compression ratios. It achieves this by performing deep pre-compression, stream detection, archiving, and decoding across various data formats. It functions by scanning files for compressed internal streams (such as Zlib, Oodle, or Deflate), temporarily decompressing them to their raw format for easier archival, and seamlessly rebuilding them during game installation.

Xtool scans the files, unpacks internal containers, decrypts proprietary headers, and unrolls zipped streams into raw, raw data.

For end-users installing a repack, the XTool library works automatically within the installer to restore files to their original state. 2. Technical Features Codec Support: It supports various modern codecs used in games, including (Kraken, Mermaid), and Advanced Operations: Deduplication:
