About 7-Zip

7-Zip is a long-running file archiver for Windows. It creates and extracts archives in its own 7z format, which is designed for a high compression ratio, and it also works with widely used formats such as ZIP, TAR and GZIP.

It adds commands to the Windows Explorer context menu, includes a simple file manager, and offers a command-line version for scripts and automation. 7z and ZIP archives can be protected with AES-256 encryption.
