It took me a while to figure out how to do this, even with the KB article.
Firstly, you need to put the macro into Normal.dotm... Open C:\Users\Yourname\AppData\Roaming\Microsoft\Templates\Normal.dotm in Word, press Alt-F11, and paste the following into Module1:
Sub BreakOnSection()
Application.ScreenUpdating = False 'Makes the code run faster and reduces screen flicker a bit.
' Used to set criteria for moving through the document by section.
Application.Browser.Target = wdBrowseSection
strBaseFilename = ActiveDocument.Name
On Error GoTo CopyFailed
'A mail merge document ends with a section break next page.
'Note: Document may or may not end with a section break,
For I = 1 To ActiveDocument.Sections.Count
'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
DocNum = DocNum + 1
strNewFileName = Replace(strBaseFilename, ".do", "_" & Format(DocNum, "000") & ".do")
ActiveDocument.SaveAs "C:\Destination\" & strNewFileName
ActiveDocument.Close
' Move the selection to the next section in the document.
Application.Browser.Next
Next I
Application.Quit SaveChanges:=wdSaveChanges
End
CopyFailed:
'MsgBox ("No final Section Break in " & strBaseFilename)
Application.Quit SaveChanges:=wdSaveChanges
End
End Sub
Save the Normal.dotm file.
Executing this code will split a document made up of multiple sections into multiple documents in the C:\Destination directory and then close down Word.
You can execute this from the command line via:
"c:\Program Files\Microsoft Office\Office12\WINWORD.EXE" /mBreakOnSection "C:\Path to Source\Document with multiple sections.doc"
To process all the .doc files in a directory, create a batch file as follows, and execute it:
@ECHO off
set "dir1=C:\Path to Source"
echo running
FOR %%X in ("%dir1%\*.doc") DO "c:\Program Files\Microsoft Office\Office12\WINWORD.EXE" /mBreakOnSection "%%~X"
echo Done
pause
