+            app.ShowPopup("File Created!");
+        }
+    }
+}//function CreateFile
+</code>
+In your app you have to do just three things,\\ \\
+. Load the Script with
+    app.LoadScript("DlgNewFile.js")
+. Create a Button to call the Dialog and add it to the layout
+    btn = app.CreateButton( "Create a new File", 0.3, 0.1, "Alum" );
+    btn.SetOnTouch(CreateNewFile);
+    lay.AddChild( btn );
+. Write a function to call the Dialog
+    function CreateNewFile()
+    {
+        // write the path where you want create the file
+        DlgNewFile = new NewFileDialog("/mnt/sdcard/");
+        DlgNewFile.Show();
+    }
+Or you can use this Example.
+<code Javascript exampleapp.js>
+//Called when application is started.
+function OnStart()
+{
+    app.LoadScript("DlgNewFile.js")
+    lay = app.CreateLayout( "Linear", "VCenter,FillXY" );
+    btn = app.CreateButton( "Create a new File", 0.3, 0.1, "Alum" );
+    btn.SetOnTouch(CreateNewFile);
+    lay.AddChild( btn );
+    app.AddLayout( lay );
+}
+//Create a new Dialog
+function CreateNewFile()
+{
+    // write the path where you want create the file
+    DlgNewFile = new NewFileDialog("/mnt/sdcard/");
+    DlgNewFile.Show();
+}
+</code>
