 ============
 
+with Original Filename
+----------------------

+Overwriting Existing File
+-------------------------
+
+By default, if the destination file already exists, a new filename will be used.

+
+.. literalinclude:: uploaded_files/022.php
+
+Check if the File Moved
+-----------------------
+

 the ``hasMoved()`` method, which returns a boolean:
 
 .. literalinclude:: uploaded_files/018.php
