: Utilizing the LZMA and LZMA2 algorithms, it typically achieves 30–70% better compression than the standard ZIP format.

: It uses AES-256 encryption to protect both the file content and the archive headers (file names), making it difficult for unauthorized users to even see what is inside without a password.

The file extension refers to a 7-Zip compressed archive, a format known for its high compression ratio and open architecture. The specific filename wxy (7).7z suggests it is likely the seventh version or copy of a container named "wxy." Key Features of the 7z Format

: Its architecture allows for the stacking of different compression, conversion, or encryption methods. Opening and Using .7z Files

: This feature treats multiple files as a single data stream to find similarities and further reduce size.
