What NanaZip is
NanaZip is a free, open-source file archiver derived from 7-Zip and made for Windows. Its modern MSIX version integrates with File Explorer context menus and file associations. The interface supports Windows 11 context menus, Fluent Design, Mica material, and dark mode. Smart Extraction treats archives with one root item differently from those with multiple root items to help keep extracted files organized. The maker lists additional formats and codecs such as Zstandard, WASM, Electron ASAR, .NET Single File bundles, Brotli, and LZ4, as well as hash algorithms including SHA-256, SHA-512, BLAKE2b, and XXH3. It 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. NanaZip 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 are unsupported. The optional Sponsor Edition addon costs $99.99, paid once and changes only the toolbar button.
