Document.Path (Word)

Returns the disk or Web path to the document.

The path doesn't include a trailing character — for example, "C:\MSOffice" or "https://MyServer" — unless requesting a path of a document stored at a network drive root (e.g. for N:\file.docx "N:\" is returned provided N is a network drive, compared to "C:" for C:\file.docx where C is a local drive). Use the PathSeparator property to add the character that separates folders and drive letters. 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.
