_Document.Path Property
Office 2010
Returns the disk or Web path to the specified object.
Assembly: Microsoft.Office.Interop.Word (in Microsoft.Office.Interop.Word.dll)
The path doesn't include a trailing character— for example, "C:\MSOffice" or "http://MyServer". Use the PathSeparator property to add the character that separates folders and drive letters. You can use the PathSeparator property to build Web addresses even though they contain forward slashes (/) and the PathSeparator property defaults to a backslash (\).
Use the Name property to return the file name without the path and use the FullName property to return the file name and the path together.
