Examples
Shows how to use the FileFormatUtil methods to detect the format of a document without any extension and save it with the correct file extension.
// 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
// The file format of this document is actually ".doc"
FileStream docStream = File.OpenRead(MyDir + "Word document with missing file extension");
FileFormatInfo info = FileFormatUtil.DetectFileFormat(docStream);

// Retrieve the LoadFormat of the document
LoadFormat loadFormat = info.LoadFormat;

// Let's show the different methods of converting LoadFormat enumerations to SaveFormat enumerations
// 
// Method #1
// Convert the LoadFormat to a String first for working with. The String will include the leading dot in front of the extension
string fileExtension = FileFormatUtil.LoadFormatToExtension(loadFormat);
// Now convert this extension into the corresponding SaveFormat enumeration
SaveFormat saveFormat = FileFormatUtil.ExtensionToSaveFormat(fileExtension);

// Method #2
// Convert the LoadFormat enumeration directly to the SaveFormat enumeration
saveFormat = FileFormatUtil.LoadFormatToSaveFormat(loadFormat);

// Load a document from the stream.
Document doc = new Document(docStream);

// Save the document with the original file name, " Out" and the document's file extension
doc.Save(
    ArtifactsDir + "File.SaveToDetectedFileFormat" + FileFormatUtil.SaveFormatToExtension(saveFormat));
