+
+## Description
+
+Learn how to save PDF files in your .NET MAUI application.
+
+This knowledge base article also answers the following questions:
+- How can I save PDF files?
+- How can I use the PDF Viewer Toolbar for Saving PDF documents?
+
+## Solution
+
+For saving files, use the [.NET MAUI File System Helper API](https://learn.microsoft.com/en-us/dotnet/maui/platform-integration/storage/file-system-helpers?view=net-maui-9.0&tabs=android). The `Save` command will be executed from a custom toolbar `ButtonToolbarItem` inside the [PDF Viewer Toolbar]({%slug pdfviewer-toolbar%}).
+
+**1.** Define the [PDF VIewer]({%slug pdfviewer-overview%}) and [PDF Viewer Toolbar]({%slug pdfviewer-toolbar%}):
+
+```XAML
+<Grid>
+	<Grid.RowDefinitions>
+		<RowDefinition Height="Auto"/>
+		<RowDefinition />
+	</Grid.RowDefinitions>
+		<telerik:RadPdfViewerToolbar PdfViewer="{Binding Source={x:Reference pdfViewer}}">
+			<telerik:ButtonToolbarItem Text="Share" Command="{Binding SaveDocumentCommand}" />
+	</telerik:RadPdfViewerToolbar>
+	<telerik:RadPdfViewer x:Name="pdfViewer" 
+						  Grid.Row="1"
+                          Document="{Binding Document, Mode=OneWayToSource}" />
+</Grid>
+```
+
+**2.** In this example, the document is loaded as `Embedded Resource`.
+
+```C#
+Func<CancellationToken, Task<Stream>> streamFunc = ct => Task.Run(() =>
+{
+	Assembly assembly = typeof(MainPage).Assembly;
+	string fileName = assembly.GetManifestResourceNames().FirstOrDefault(n => n.Contains("pdf-overview.pdf"));
+	Stream stream = assembly.GetManifestResourceStream(fileName);
+	return stream;
+});
+this.pdfViewer.Source = streamFunc;
+```
+
+**3.** Create a `ViewModel` and implement the `ShareDocumentCommand` which defines the Share API:
+
+```C#
+public class ViewModel
+{
+	public ViewModel()
+	{
+		this.SaveDocumentCommand = new Command(this.SaveDocument);
+	}
+
+	// save pdf document
+	private void SaveDocument(object obj)
+	{
+
+		var fileName = "document.pdf";
+		var localFolder = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData);
+		var filePath = Path.Combine(localFolder, fileName);
+
+		using (Stream output = File.OpenWrite(filePath))
+		{
+			new Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.PdfFormatProvider().Export(this.Document, output);
+
+			Application.Current.MainPage.DisplayAlert("Document is saved to local application data: ", filePath, "OK");
+		}
+	}
+
+	public RadFixedDocument Document { get; set; }
+
+	public ICommand SaveDocumentCommand { get; set; }
+}
+```
+
+> Make sure the app is granted permissions to access local data.

+This knowledge base article also answers the following questions:
+- How can I transfer PDF files in .NET MAUI application?

+
+## Solution
+
+For sharing files, use the [.NET MAUI Share File API](https://learn.microsoft.com/en-us/dotnet/maui/platform-integration/data/share?view=net-maui-9.0&tabs=android). The `Share` command will be executed from a custom toolbar `ButtonToolbarItem` inside the [PDF Viewer Toolbar]({%slug pdfviewer-toolbar%}).

+
+		<telerik:ButtonToolbarItem Text="Share" 
+                                   Command="{Binding ShareDocumentCommand}" />
+	</telerik:RadPdfViewerToolbar>

+	{
+		await ShareAsync();
+	}
+
+	// share pdf document
+	private async Task ShareAsync()
+	{
+		Assembly assembly = typeof(MainPage).Assembly;
+		string fileName = assembly.GetManifestResourceNames().FirstOrDefault(n => n.Contains("pdf-overview.pdf"));
+		Stream stream = assembly.GetManifestResourceStream(fileName);
+		var cacheFile = Path.Combine(FileSystem.CacheDirectory, "pdf-overview.pdf");
+		using (var file = new FileStream(cacheFile, FileMode.Create, FileAccess.Write))
+		{
+			stream.CopyTo(file);
+		}
+		var request = new ShareFileRequest
+		{
+			Title = "Share pdf document",
+			File = new ShareFile(cacheFile)

+		await Share.Default.RequestAsync(request);
+	}
+
+	public RadFixedDocument Document { get; set; }
+
