[bb].7z Info

The .7z extension represents a high-compression, open-source archive format managed primarily by 7-Zip software, offering superior compression ratios via LZMA/LZMA2, AES-256 encryption, and support for massive archive sizes. While Windows 11 provides native support, the official 7-Zip application offers advanced features like solid compression, self-extracting archives, and robust command-line operations.
