1.) Does reading/manipulating/saving word doc using DocIO gives better performance than OpenXml?  
2.) Is DocIO built on OpenXML, or it uses its own framework? 

Essential DocIO using its own implementation for opening and saving document. 
DOCX format document is a zip archive file with extension “docx”, Essential DocIO internally decompress it with their own compression library and populate the content in the document object model utilizing remarkable main memory. DocIO doesn’t build on OpenXML and not need OpenXML as dependent to using DocIO in your machine. We have implemented our own parsing and serializing using XmlReader and XmlWriter. So, it takes some considerable time while compare with OpenXML. 


3.) Can I modify an existing Template file(.dotx, .potx) and save it as word(.docx) or presentation(.ppt) file respectively
