NanaZip
What it is
NanaZip is a free, open-source file archiver derived from 7-Zip and focused on Windows. Its modern MSIX version works with File Explorer context menus and file associations, while the interface supports Windows 11 context menus, Fluent Design, Mica material, and dark mode. Smart Extraction handles archives with one root item differently from archives with several root items to keep extracted files organized. Listed formats and codecs include Zstandard, WASM, Electron ASAR, .NET Single File bundles, Brotli, and LZ4. Additional hashes include SHA-256, SHA-512, BLAKE2b, and XXH3. NanaZip offers archive encryption, split archives, command-line tools, and a 7-Zip execution alias. Security measures include package integrity checks, Control Flow Guard, Shadow Stack compatibility, limits on dynamic code generation, and blocking unexpected remote libraries. It supports Windows 10 version 2004 or later and Windows Server 2022 or later on x64 and ARM64.
