: Archiving multiple small "greeting" or "summary" files into one greetsum.7z makes them faster to email or upload.
A .7z file is a high-compression archive format developed by Igor Pavlov. It is known for its open architecture and high efficiency, often achieving 30–70% better compression than the standard ZIP format.
