⚠️ : These settings are extremely slow (hours for large games) and require high RAM. For daily use, reduce dict to 512 MB and use LZMA:5. 5. Example Configuration File ( xcfg.ini ) [Arc] CompressionLevel=9 DictionarySize=1024 Solid=on SolidBlockSize=0 CompressionMethod=lzma2 SecondaryMethod=ppmd:8 Filters=bcj2,rep:127:512m MemoryLock=on Threads=0 6. Testing Your Settings Use a small folder (e.g., 500 MB of mixed files) to test:
| Setting | Value | |---------|-------| | | -m9 (maximum compression) | | Dict size | -md=1024m (1GB) | | Solid block | -ms=off or very large block | | Compressor | -mcp=lzma:6 + -mpp=ppmd:8 (or LZMA2 + PPMD) | 2. Optimal Command Line for Best Ratio Use this in xTool.exe or xcfg.ini : xtool razor12911 compression settings best ratio
