Step 3: Retrieve File Format Properties

Now, you can access various properties of the PDF file format using the PdfRootPackage object:

Extract File Format Information

Console.WriteLine("File Format: " + root.FileType.FileFormat);

Extract Version Information

Console.WriteLine("Version: " + root.FileType.Version);

Extract MIME Type

Console.WriteLine("MIME Type: " + root.FileType.MimeType);

Extract File Extension

Console.WriteLine("Extension: " + root.FileType.Extension);
