NanaZip

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.

All kinds of contributions will be appreciated. All suggestions, pull requests, and issues are welcome.

If you want to sponsor the development of NanaZip, please read the document of NanaZip Sponsor Edition. It's free for all NanaZip source code repository contributors.

In general, NanaZip Sponsor Edition is more like contributor's edition, but we provide a way to buy the honor and make someone look like a source code contributor, because NanaZip is always a community-friendly open-source project.

If you'd like me to add features or improvements ahead of time, please use paid services.

Besides NanaZip.org, NanaZip's official project pages are only hosted on GitHub, Microsoft Store, My Digital Life Forums, SourceForge, and Windows App Community.

Differences between NanaZip and NanaZip Classic

NanaZip plans to have two distribution flavors called NanaZip and NanaZip Classic. Here are the differences between them.

• NanaZip (Modern)

  • Only MSIX packaged version.
  • Support the context menu in Windows 10/11 File Explorer.
  • Support the file associations.
  • Provide 7-Zip execution alias for helping users to migrate to NanaZip.
  • XAML-based GUI.

• NanaZip Classic (Work In Progress)

  • Only portable version which is suitable for Server Core, Windows PE, Windows RE, and Wine.
  • Don't have the context menu support.
  • Don't have the file associations support.
  • Don't have the 7-Zip execution alias support.
  • Win32 GUI.

[!CAUTION] NanaZip can be used as portable version if you use the official portable release package. It's designed for debugging/testing/development purpose and scenarios (a.k.a. Server Core, Windows PE, Windows RE, and Wine) really need portable version. But please note that some features is not available, such as context menu and file associations. Some issues will not be fixed if you are using NanaZip in portable mode.

[!CAUTION] We don't provide any support for users if they are using any non-official release packages, such as extracting the files from the MSIX package or copy from the NanaZipPackage project output. For example, if you are using the files extracted from the MSIX package of NanaZip like Scoop package manager does. We hugely recommend you to use the official release packages of NanaZip. For example, WinGet package manager uses NanaZip official release package to install NanaZip.

System Requirements

Here are the system requirements starting with NanaZip 6.0:

• Supported Operating Systems:
  • Windows 10, version 2004 (Build 19041) or later
  • Windows Server 2022 (Build 20348) or later
• Supported Platforms:
  • x86 (64-bit)
  • ARM (64-bit)

In general, NanaZip follows the 2025 baseline defined by Kenji Mouri's document, read MD23: The baselines of Windows targets for all my open-source projects for more information.

Note: Due to the Self Extracting Executables (SFX) will be migrated to x86 (64-bit) starting with NanaZip 6.0, it gives users chances to use Self Extracting Executables (SFX) archives under 64-bit Microsoft official Windows PE and Windows RE instances:

• For ARM (64-bit) Microsoft official Windows PE and Windows RE, you need to make sure you Windows PE and Windows RE images are built with Windows ADK Build 25398 or later and integrated the x64 emulation optional component.
• For ARM (64-bit) Windows 10, I suggest you to upgrade to Windows 11 because ARM (64-bit) Windows 11 provides x64 emulation support, and Windows 10 is nearly end of support from Microsoft.

We chose Windows as the major platform for the NanaZip project supported because Windows has maintained a good and proven ABI and compatibility, and stands out in the history of computing. But we also care about the non-Windows platform. Here are the policy for non-Windows platform support:

• The modern flavor of NanaZip won't support non-Windows unless someone ported WinRT XAML to POSIX. So, non-Windows support policy is only for NanaZip Core and NanaZip Classic.
• The developer team will try best to support Wine which has the Windows Vista or later feature level. Currenly tested simply under Wine 9.x.
• We don't support ReactOS and its derivatives because they are too hard to support. But testing under the ReactOS and its derivatives may be interesting.

[!NOTE] In theory, NanaZip Classic can run on Windows 10 (Build 10240) or later if ucrtbase.dll in the System32 folder has been replaced with version 10.0.19041.0 or later. However, this is a high-risk operation and is not recommended.

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 the stable release, and NanaZip Preview for the preview release.

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

• NanaZip
• NanaZip Preview

MSIX Package

You can download the MSIX package and the corresponding XML license file from GitHub Releases. After you have finished downloading the relevant files, you can use one of the methods described below to install NanaZip:

[!NOTE] All required dependencies are bundled with NanaZip's MSIX package, as users without access to the Microsoft Store may have difficulty obtaining them separately. This is intended to make NanaZip more robust and easier to deploy in a wide range of environments.

App Installer

According to Install and update the App Installer - MSIX | Microsoft Learn, we will know that the App Installer ships as part of Windows SKUs which can access to the Microsoft Store, or you can follow the instructions in the document to install the App Installer if your Windows SKUs doesn't have access to the Microsoft Store.

If your environment has the App Installer, you can double click the MSIX package to install NanaZip.

[!CAUTION] If NanaZip is installed using this method without an Internet connection, you must connect to the Internet and launch it once so that Windows can acquire the required license. Otherwise, NanaZip may not launch properly.

Command Line (With license file)

If your downloaded NanaZip release provides the XML license file, you can use the following command to install NanaZip for all users.

If you open the PowerShell as Administrator, you can execute:

Add-AppxProvisionedPackage -Online -PackagePath The path of the MSIX package -LicensePath The path of the XML license file

If you open the Command Prompt as Administrator, you can execute:

PowerShell -NoLogo -NoProfile -NonInteractive -InputFormat None -ExecutionPolicy Bypass Add-AppxProvisionedPackage -Online -PackagePath The path of the MSIX package -LicensePath The path of the XML license file

Or you can execute:

DISM.exe /Online /Add-ProvisionedAppxPackage /PackagePath:The path of the MSIX package /LicensePath:The path of the XML license file

If you want to uninstall NanaZip if you installed it with this method, you can use the following command to uninstall NanaZip.

If you open the PowerShell as Administrator, you can execute:

Get-AppxPackage -Name 40174MouriNaruto.NanaZip -AllUsers | Remove-AppxPackage -AllUsers -Confirm

Command Line (Without license file)

If your downloaded NanaZip release doesn't provide the XML license file, or you don't want to install NanaZip for all users, you can use the following command to install NanaZip for the current user.

If you open the PowerShell as Administrator, you can execute:

Add-AppxPackage -DeferRegistrationWhenPackagesAreInUse -ForceUpdateFromAnyVersion -Path The path of the MSIX package

If you open the Command Prompt as Administrator, you can execute:

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

[!CAUTION] If NanaZip is installed using this method without an Internet connection, you must connect to the Internet and launch it once so that Windows can acquire the required license. Otherwise, NanaZip may not launch properly.

Known issues

• If you can't find NanaZip in the context menu, please restart all File Explorer processes via Task Manager.
• Due to the design of MSIX, drives' context menu in Explorer only show in Windows 11, version 22H2 or later.
• Due to the Microsoft Store limitations, NanaZip 1.2 and later won't support languages not mentioned in https://docs.microsoft.com/en-us/windows/uwp/publish/supported-languages.
• If you turn off the Windows Firewall, NanaZip may fail to install. (https://github.com/M2Team/NanaZip/issues/204) (https://github.com/microsoft/terminal/issues/12269)
• Due to the System Settings limitations, starting with Windows 11+ (Build 22000.1817+ & 22621.1555+), you can launch directly to the Settings page for file association for NanaZip. (https://learn.microsoft.com/en-us/windows/uwp/launch-resume/launch-default-apps-settings)
• Due to the Microsoft Store Licensing API implementation, you will find NanaZip will try to access the Internet beginning with NanaZip 3.0 because NanaZip needs to use that to check the Sponsor Edition addon licensing status.
• For optimizing the user experience, NanaZip will only check the Sponsor Edition addon licensing status at the first time your launch NanaZip File Manager. You can click the sponsor button if you want to refresh the status after you have purchased or redeemed the Sponsor Edition addon.
