This is the File attribute to be used when defining a filename-related property, indicating that the property is a file path, and can invoke the OpenFile dialog in Visual Signal. The filters used in OpenFile dialog can be specified using the standard "|"-separated .Net filter specification in [filter]. For example: "Text files (*.txt)|*.txt|All files (*.*)|*.*", or "Image Files(*.BMP;*.JPG;*.GIF)|*.BMP;*.JPG;*.GIF|All files (*.*)|*.*"
