Xtool solves this problem via . It scans files, detects existing compressed streams, decodes them back to their raw, uncompressed state, and saves instructions on how to rebuild them. When the final archiver processes this "raw" data, it achieves exponentially higher compression ratios. Core Technical Features
Native integration with the zstd engine to manage block-level differences. xtool library by razor12911 repack
: A mode designed to increase processing speed by bypassing integrity checks on non-essential streams, though it is typically disabled for encryption-related codecs to prevent data corruption. Oodle Scanner Optimization Xtool solves this problem via
: A tool like 7-Zip, FreeArc, or Lolz compresses the Xtool output. Extraction detects existing compressed streams
XTool addresses this barrier by acting as a "pre-processor":
