What is it?

NanaZip is a file archiver for Windows, forked from the 7-Zip source code. It keeps 7-Zip's compression and archive format support while adding a modern interface: a XAML-based GUI with dark mode, the Mica effect on the main window, and per-monitor DPI awareness. It integrates with the Windows 10/11 File Explorer context menu and is distributed as an MSIX package through the Microsoft Store, GitHub Releases, and other channels.

Beyond 7-Zip's features, NanaZip adds many hash algorithms (including SHA3, BLAKE2b, xxHash and SM3), extra codecs such as Zstandard, Brotli and LZ4, and read-only support for several file system images and bundle formats. It also enables additional security mitigations such as Control Flow Guard and CET Shadow Stack in its binaries.

The project targets 64-bit Windows 10 (2004) or later and Windows Server 2022, on x86-64 and ARM64. A portable Classic edition for environments like Windows PE, Server Core and Wine is described as work in progress.

  • 01Dark mode and Mica effect across the GUI, built with XAML.
  • 02Windows 10/11 File Explorer context menu integration.
  • 03Distributed as MSIX with bundled dependencies for modern deployment.
  • 04Adds hash algorithms such as SHA3, BLAKE2b, xxHash and SM3.
  • 05Adds codecs including Zstandard, Brotli and LZ4 on top of 7-Zip formats.
  • 06Read-only support for formats such as asar, UFS and WebAssembly binaries.

Use cases

  • Replacing 7-Zip on Windows 10/11 for users who want a modern, native-looking interface.
  • Verifying file checksums with a broader set of hash algorithms from the Explorer menu.
  • Opening Electron asar archives or certain firmware and file system images without extra tools.
  • Deploying a compression tool across managed Windows machines via MSIX.
