            // Load the document without a file extension into a stream and use the DetectFileFormat method to detect it's format. These are both times where you might need extract the file format as it's not visible

            //
            // Method #1
            // Convert the LoadFormat to a string first for working with. The string will include the leading dot in front of the extension.
