The FullFileName property returns the filename and file path where a document is saved. See also the Document.Title property.
Examples:
The following VBA example shows the path and filename of the document if the document has been saved to a file.
Sub Test()
If ActiveDocument.FullFileName = "" Then
MsgBox "Current document is not saved yet"
Else
MsgBox "Current document was saved to: " & ActiveDocument.FullFileName
End If
End Sub
