NanaZip

What NanaZip is

NanaZip is a free, open-source file archiver derived from 7-Zip and focused on Windows. Its modern MSIX version integrates 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 those with multiple root items to help keep extracted files organized. The maker lists formats and codecs including Zstandard, WASM, Electron ASAR, .NET Single File bundles, Brotli, and LZ4. Additional hash algorithms include SHA-256, SHA-512, BLAKE2b, and XXH3. NanaZip also provides command-line tools and a 7-Zip execution alias. Listed 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. Experimental portable releases omit some features, including File Manager, and receive no support. A separate Sponsor Edition addon costs $99.99, paid once and only changes the toolbar button.
