7-Zip vs NanaZip

7-Zip is a file archiver for Windows, Linux, and macOS, offered at free with no registration or payment required. It creates and extracts 7z, XZ, BZIP2, GZIP, TAR, ZIP, and WIM archives, and can extract additional formats such as RAR, ISO, and VHDX. The 7z format uses LZMA and LZMA2 compression, and AES-256 encryption is available for 7z and ZIP files. Other listed capabilities include split archives, archive repair, portable use, and command-line tools. The Windows version includes Shell integration, a file manager, a command-line version, and a FAR Manager plugin. The software is open source; most code is under the GNU LGPL, with some under BSD licenses and an unRAR restriction applying to some parts. The maker says it can be used in commercial organizations without payment. It is localized in 87 languages. Developers can use the LZMA SDK, which includes documentation, samples, headers, libraries, and tools for applications using LZMA compression.

NanaZip is a free, open-source file archiver derived from 7-Zip and built for Windows. Its modern MSIX version connects 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 treats archives with one root item differently from those with several root items to keep extracted files organized. The maker lists formats and codecs including Zstandard, WASM, Electron ASAR, .NET Single File bundles, Brotli, and LZ4. Additional hashes include SHA-256, SHA-512, BLAKE2b, and XXH3. Command-line tools and a 7-Zip execution alias are included. Listed protections 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.
