What is a .msix file?

MSIX is a Windows app package format that provides a modern packaging experience to all Windows apps. It enables developers to package their applications in a single package format for distribution through the Microsoft Store or other channels. MSIX packages are designed to be reliable, secure, and efficient, offering features like automatic updates, clean uninstallations, and reduced disk space usage. The format supports both Win32 and Universal Windows Platform (UWP) applications, making it a versatile choice for developers targeting the Windows ecosystem. MSIX aims to replace older packaging formats like MSI and APPX, offering improved security and deployment capabilities. It supports a variety of installation scenarios, including sideloading and enterprise deployment. The format also includes features for managing application dependencies and ensuring that applications are isolated from each other, enhancing system stability and security. MSIX packages are digitally signed to verify the publisher's identity and ensure that the application has not been tampered with.
