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.

Differences between NanaZip and NanaZip Classic

NanaZip 3.0 and onwards will have two distribution flavors called NanaZip and NanaZip Classic. Here are the differences between them.

NanaZip
- Only 64-Bit support.
- 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.
- Only support Windows 10 Version 2004 (Build 19041) or later.
- XAML-based GUI.
NanaZip Classic
- Have 32-Bit support.
- Only portable version.
- Don't have the context menu support.
- Don't have the file associations support.
- Don't have the 7-Zip execution alias support.
- Support Windows Vista RTM (Build 6000.16386) or later.

System Requirements

NanaZip (XAML-based GUI and MSIX package)
- Supported OS: Windows 10 Version 2004 (Build 19041) or later
- Supported Platforms: x86 (64-bit) and ARM (64-bit)
NanaZip Classic (Win32 GUI)
- Supported OS: Windows Vista RTM (Build 6000.16386) or later
- Supported Platforms: x86 (32-bit and 64-bit) and ARM (64-bit)
NanaZip Core (Core, Codecs, CLI and the Self Extracting Executables)
- Supported OS: Windows Vista RTM (Build 6000.16386) or later
- Supported Platforms: x86 (32-bit and 64-bit) and ARM (64-bit)

Note: Except the Self Extracting Executables, the ucrtbase.dll with 10.0.19041.0 version or later need to be existed in the binary folder if you want to use NanaZip components on Windows versions earlier than Windows 10 Version 2004 (Build 19041).

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.

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.

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 PowerShell which is run as administrator.

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

Note: 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.

If you want to install NanaZip for all users, you can execute the following command in the PowerShell which is run as administrator.

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

You also can execute the following command in the Command Prompt which is run as administrator instead.

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

For more information, please read documents for PowerShell and DISM

Note: Due to the policy from Microsoft Store, you need to run NanaZip with the internet connection at the first time for getting the license if you install NanaZip without the internet connection, otherwise Windows won't launch NanaZip properly.

If you want to uninstall NanaZip you installed for all users, you can execute the following command in the PowerShell which is run as administrator.

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

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(22H2)+.
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.
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. (#204) (microsoft/terminal#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.
