NanaZip

Warning: This project is in early stages of development, the final product may differ from what you see now.

NanaZip is an open source file archiver intended for the modern Windows experience, forked from the source code of well-known open source file archiver 7-Zip.

We need help to translate NanaZip into native languages that have not been supported.

Features

Inherit all features from 7-Zip 21.06.
Packaging with MSIX for modern deployment experience.
Support the context menu in Windows 10/11 File Explorer.
Enable NSIS script decompiling support for the NSIS archives. (Merged from 7-Zip NSIS branch.)
Provide 7-Zip execution alias for helping users to migrate to NanaZip.
Support the Brotli, Fast-LZMA2, Lizard, LZ4, LZ5 and Zstandard codecs. (Merged from 7-Zip ZS branch.)

System Requirements

Supported OS: Windows 10, version 1809 or later
Supported Platforms: x86, x86-64(AMD64) and ARM64.

Download and Installation

Here are some available installation methods for NanaZip.

Microsoft Store

This is the recommended way to install NanaZip.

Search and install NanaZip in Windows Store for stable release, and NanaZip Preview for preview release.

Also, you can also click the Microsoft Store link you needed.

MSIX Package

You also can download the MSIX Package in GitHub Releases.

After you have downloaded the MSIX Package, you can double click to install it, or you can execute the following command in the Command Prompt which is run as the Administrator.

PowerShell -NoLogo -NoProfile -NonInteractive -InputFormat None -ExecutionPolicy Bypass Add-AppxPackage -Path The path of the MSIX package

P.S. All needed dependencies are included in the MSIX Package of NanaZip because we known that it's very difficult for users who do not have access to the store to get our dependency packages, and we want to be robust and deployable everywhere.

Known issues

You may meet the application crash in some cases in NanaZip 1.0 Preview 1 and NanaZip 1.0 Preview 2 because there are some issues in the exception handler implementation from VC-LTL 5.x. NanaZip 1.0 Preview 3 will be fixed the issue because mingkuang (the author of VC-LTL) has released the new version of VC-LTL.
Windows may show the contrast white icon in the taskbar when you using the contrast standard mode in NanaZip 1.0 Preview 1 and NanaZip 1.0 Preview 2 is fixed the issue.
If you can't find NanaZip in the context menu, please restart all File Explorer processes via Task Manager.
Due to the issues in Desktop Bridge file system virtualization, you are unable to use NanaZip in the Safe Mode of Windows.
Due to the policy from Microsoft Store, NanaZip is unable to disable Desktop Bridge file system virtualization, so the file operations in %UserProfile%/AppData will be redirected in Windows 10, and file operations in directories other than Local, LocalLow and Roaming in %UserProfile%/AppData will still be redirected in Windows 11.

Development Roadmap

1.0 (December 8, 2021)
- Modernize the build toolchain with MSBuild for using MSIX packaging and parallel compilation support.
- Use VC-LTL 5.x toolchain to make the binary size even smaller than the official 7-Zip because we can use ucrtbase.dll directly and the optimizations from modern compile toolchain.
- Add the context menu support in Windows 10/11 File Explorer.
- New icons and minor UI tweaks.
- Merge NSIS script decompiling support from 7-Zip NSIS branch. (Suggested by alanfox2000.)
