You can't access the local, roaming, or temporary folders through the file picker. In addition, and unlike other locations, you can also access files in your app data locations by using some Win32 and COM for UWP apps and some C/C++ Standard Library functions from Visual Studio. You can learn more about using app URIs in How to load file resources. To access files in the app's roaming or temporary folders use 'ms-appdata:///roaming/' or 'ms-appdata:///temporary/' instead. The 'ms-appdata:///local/' prefix in the URI refers to the app's local folder. When GetFileFromApplicationUriAsync completes, it returns a StorageFile that represents the file.txt file in the app's local folder ( file in the example). Windows::Storage::StorageFolder installedLocation)Īuto getFileTask = create_task(StorageFile::GetFileFromApplicationUriAsync(ref new Uri('ms-appdata:///local/file.txt')))

Var installDirectory = .installedLocation You can retrieve a StorageFolder that represents your app's install directory, like this: installedLocation = .InstalledLocation There are two primary ways to access files and folders in your app's install directory: The folder where your app is installed on the user's system. When you create a new app, you can access the following file system locations by default: Application install directory Apps can also access additional locations through the file picker, or by declaring capabilities.

Universal Windows Platform (UWP) apps can access certain file system locations by default.
