Here are some available installation methods for NanaZip.

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.

• NanaZip
• NanaZip Preview

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

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.

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 -SkipLicense

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 /SkipLicense

For more information, please read documents for PowerShell and DISM

P.S. 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

• 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.
• 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.

  • Try to contribute recovery record support for 7z archives to 7-Zip mainline. (Suggested by SakuraNeko.)
  • Try to port NanaZip to Linux.
    • Try to port MegaUI (an developing lightweight UI framework created by mingkuang, under internal developing at the current stage, will be open source if the work has done) framework to Linux.
    • Try to create MinLin (a.k.a. Minimum Linux, a distro intended for helping publish distroless binaries and provide some Windows API functions as static libraries for having a lightweight platform abstraction layer) project because I think NanaZip should support distroless environment for reducing time wasting for compiling for different distros.
  • After porting NanaZip to Linux, accept contributions from community folks for other POSIX platforms (e.g. FreeBSD) and macOS support.
  • Try to add extension for Windows File Explorer for give user immersive experience like builtin zip file support in Windows. (Suggested by SakuraNeko and shuax.)
