![]() StorageFolder newFolder = await DownloadsFolder.CreateFolderAsync("New Folder") You can create a subfolder in the user's Downloads folder like this: using Windows.Storage This file is called newFile in the example. When these methods complete, they return a StorageFile that represents the file that was created. CreateFileAsync is overloaded so that you can specify what the system should do if there is already an existing file in the Downloads folder that has the same name. ("file.txt").done(Ĭo_await Windows::Storage::DownloadsFolder::CreateFileAsync(L"file.txt")Īuto createFileTask = create_task(DownloadsFolder::CreateFileAsync(L"file.txt")) ĬreateFileTask.then((StorageFile^ newFile)ĭownloadsFolder. StorageFile newFile = await DownloadsFolder.CreateFileAsync("file.txt") You can create a file in the user's Downloads folder like this: using Windows.Storage However, you can gain access to files and folders in the user's Downloads folder by calling a file picker ( FileOpenPicker or FolderPicker) so that users can navigate and pick files or folders for your app to access. The folder where downloaded files are saved by default.īy default, your app can only access files and folders in the user's Downloads folder that your app created. Learn how to use the file picker in Open files and folders with a picker.įor more info about accessing an SD card or other removable devices, see Access the SD card. Of course, you can also gain access to files and folders on a removable device by calling the file picker (using FileOpenPicker and FolderPicker) and letting the user pick files and folders for your app to access. The files your app can access are limited to specific file types that are specified via File Type Association declarations in your app manifest. This is an option if your app uses the AutoPlay extension to launch automatically when users connect a device, like a camera or USB thumb drive, to their system. Access removable devicesĪdditionally, your app can access some of the files on connected devices by default. 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.
