How to paste the split word document into target bookmarks

Hi, 

I want to split a big word document by section break into target documents with target bookmarks(The section from the big wor document should be pasted to another documents after a bookmark in the target document and similarly for other documents)

I used this code to split but I want to target dedicated files in a dedicated folder. 

What should I be doing?

Here's the split code:

Sub BreakOnSection()
   ' Used to set criteria for moving through the document by section.
   Application.Browser.Target = wdBrowseSection

   'A mailmerge document ends with a section break next page.
   'Subtracting one from the section count stop error message.
   For i = 1 To ((ActiveDocument.Sections.Count) - 1)
   
      'Select and copy the section text to the clipboard
      ActiveDocument.Bookmarks("\Section").Range.Copy

      'Create a new document to paste text from clipboard.
      Documents.Add
      Selection.Paste

   ' Removes the break that is copied at the end of the section, if any.
      Selection.MoveUp Unit:=wdLine, Count:=1, Extend:=wdExtend
      Selection.Delete Unit:=wdCharacter, Count:=1

     ChangeFileOpenDirectory "C:\"
      DocNum = DocNum + 1
     ActiveDocument.SaveAs FileName:="test_" & DocNum & ".doc"
     ActiveDocument.Close
      ' Move the selection to the next section in the document
     Application.Browser.Next
   Next i
   ActiveDocument.Close savechanges:=wdDoNotSaveChanges
End Sub

Thanks in advance.
