If you prefer using the command line ( 7z.exe ), you can "generate" an ultra-compressed archive with specific parameters to ensure the best result:
: Increase this (e.g., to 64MB or higher) if you have enough RAM. A larger dictionary allows the archiver to find more patterns in the data, leading to a "better" (smaller) piece of compressed data. CGV.7z
: Use LZMA2 , which is faster and more efficient for modern multi-core processors. If you prefer using the command line ( 7z
To "generate a good piece" using the 7z compression tool, you should focus on optimizing the compression parameters to achieve the smallest file size possible while maintaining data integrity. 7-Zip’s native algorithm is highly efficient, often reducing file sizes by 30–70% more than standard ZIP formats.

-ms=on : Enables solid archiving for better overall compression.
