If the same file exists in multiple MSIX packages, the OS stores the shared file on disk only once and create hard links from both packages to the shared file. When a user downloads an MSIX package, the AppxManifest.xml is used to determine if the data contained with the package already exist on disk from an earlier package installation. In order to avoid duplication of files to optimize for disk storage space and reduce the bandwidth needed when downloading files, the OS leverages single storage and hard linking of files. The operating system (OS) supports different levels of file system operations for packaged desktop applications, depending on the folder location. Windows prevents apps from launching if these files are tampered with. When that application is launched, it does not run inside an app container, but instead it runs as the user as it normally would.Īfter deployment, package files are marked read-only and heavily locked down by the operating system. Inside that manifest file is an element, which references the full-trust app. Each package folder contains a manifest (named AppxManifest.xml) that contains a special XML namespace for packaged apps. App packages are installed under C:\Program Files\WindowsApps\package_name, with the executable titled app_name.exe. InstallationĪpp packages are installed on a per user basis instead of system wide.
This allows them to interact with other apps the same way classic desktop applications do.
Packages that you create for your desktop application are desktop-only, full-trust applications and are not virtualized or sandboxed.

Windows 10 accomplishes this by placing the application inside a MSIX package, and then detecting and redirecting some changes it makes to the file system and registry at runtime. This article provides a deeper dive on what happens to files and registry entries when you create a Windows app package for your desktop application.Ī key goal of a modern package is to separate application state from system state as much as possible while maintaining compatibility with other apps.
