File search sample

Shows how to query files in a location (like a folder, library, device, or network location). Uses the Windows.Storage.Search API.

Note: This sample is part of a large collection of UWP feature samples. If you are unfamiliar with Git and GitHub, you can download the entire collection as a ZIP file, but be sure to unzip everything to access shared dependencies. For more info on working with the ZIP file, the samples collection, and GitHub, see Get the UWP samples from GitHub. For more samples, see the Samples portal on the Windows Dev Center.

Important APIs in this sample include:

• QueryOptions class
• StorageFileQueryResult class
• StorageFolder.CreateFileQueryWithOptions method

For a walkthrough, see Quickstart: Accessing files programmatically.

Note The Windows universal samples require Visual Studio 2017 to build and Windows 10 to execute.
