Remarks

Use a value from the CommonFolderQuery enumeration when you call one of the following methods of the StorageFolder class. For examples that use values from the CommonFolderQuery enumeration, see the topics for these methods.

These methods use the value from the CommonFolderQuery enumeration to initialize the DateStackOption, FolderDepth, IndexerOption, and SortOrder options of the query.

Call the StorageFolder.IsCommonFolderQuerySupported method to determine whether the CommonFolderQuery value that you want to use is available for the current folder.

Tip

When a query groups files into virtual folders based on a property that can have multiple values (for example, System.Author), a particular file may appear in more than one virtual folder because each folder represents one of the multiple values.

Files that don't have a value for the property that the query uses to group files are typically excluded from query results.
