This sample shows how to access files and folders by letting the user choose them through the file pickers and how to save a file so that the user can specify the name, file type, and location of a file to save. This sample uses Windows.Storage.Pickers and Windows.Storage API.
The sample demonstrates these tasks:
-
Let the user pick one file to access
Uses the FileOpenPicker.PickSingleFileAsync method (or PickSingleFileAndContinue) to call a file picker window and let the user pick a single file. For a walkthrough of this task, see Quickstart: Accessing files with file pickers (HTML or XAML).
-
Let the user pick multiple files to access
Uses the FileOpenPicker.PickMultipleFilesAsync method (or PickMultipleFilesAndContinue) to call a file picker window and let the user pick multiple files. For a walkthrough of this task, see Quickstart: Accessing files with file pickers (HTML or XAML).
-
Let the user pick one folder to access
Uses the FolderPicker.PickSingleFolderAsync method (or PickFolderAndContinue) to call a file picker window and let the user pick multiple files. For a walkthrough of this task, see Quickstart: Accessing files with file pickers (HTML or XAML).
-
Let the user save a file and specify the name, file type, and/or save location
Uses the FileSavePicker.PickSaveFileAsync method (or PickSaveFileAndContinue) to call a file picker window and let the user pick multiple files. For a walkthrough of this task, see How to save files through file pickers (HTML or XAML).
-
Let the user pick a locally cached file to access
The user may choose access a file that is provided by another app (the providing app) that participates in the Cached File Updater contract. Like the first scenario, this scenario uses the FileOpenPicker to access these files and to show how the providing app (the File picker contracts sample) can interact with the user through the file picker if necessary, for example if credentials are required to access the file.
Note This scenario requires the File picker contracts sample.
-
Let the user save a locally cached file
The user may choose save a file that was provided by another app (the providing app) that participates in the Cached File Updater contract. This scenario uses the FileSavePicker and the CachedFileManager to let the user save a file to another app (the File picker contracts sample) and how the providing app can interact with the user through the file picker if necessary, for example if there is a version conflict.
Note This scenario requires the File picker contracts sample.

- If you download the samples ZIP, be sure to unzip the entire archive, not just the folder with the sample you want to build.
- Start Microsoft Visual Studio 2015 and select File > Open > Project/Solution.
- Starting in the folder where you unzipped the samples, go to the Samples subfolder, then the subfolder for this specific sample, then the subfolder for your preferred language (C++, C#, or JavaScript). Double-click the Visual Studio 2015 Solution (.sln) file.
- Press Ctrl+Shift+B, or select Build > Build Solution.
The next steps depend on whether you just want to deploy the sample or you want to both deploy and run it.
- Select Build > Deploy Solution.
- To debug the sample and then run it, press F5 or select Debug > Start Debugging. To run the sample without debugging, press Ctrl+F5 or select Debug > Start Without Debugging.
