A Document object represents each open document or designer in the environment — that is, windows that are not tool windows and have an area to edit text. The Document object has members (properties, methods, and events) that you can use to manipulate the document. If it is a text file edited by the Visual Studio editor, then it also has a TextDocument object associated with it.
All open documents are referenced in the Documents collection. You can find a particular document by iterating through this collection.
The default property for a Document object is the Name property.
Reference this object by using DTE.Documents.Item(...).
