I have read that master documents are not good. But for now I want to give it
try but still be on the safe side. By writing some VBA code to take a number
of files make a subfolder, copy all relevant files there and then create a
master document there. So it does not matter if the master document corrupts
some files since they are just copies of the original anyway. Plus I can make
different editions of the book I am working on putting together. The editions
must have some different formating and so on. Anyway I have gotten folder and
file handling to work fine for me. Although when I try to run the following
code.

Sub makeEdition(currPath As String, dirName As String, ByRef filesToCopy As
Collection)
   makeDirAndFillIn currPath:=currPath, dirName:=dirName,
filesToCopy:=filesToCopy
   ChDir path:=currPath
   Documents.Add Template:=currPath & "\Chapter-template.dot"
   Dim masterName As String
   masterName = currPath & "\" & dirName & "\master.doc"
   ActiveDocument.SaveAs fileName:=masterName,
FileFormat:=wdFormatDocument, _
       EmbedTrueTypeFonts:=False, SaveNativePictureFormat:=False,
SaveFormsData:=False, _
       SaveAsAOCELetter:=False
   
   Dim masterDoc As Document
   Dim masterDocRange As Range
   
   Set masterDoc = Documents("master.doc")
   
   Set masterDocRange = masterDoc.Range
   masterDocRange.Collapse direction:=wdCollapseStart
   
   
   ActiveWindow.ActivePane.View.Type = wdMasterView
   
   Dim subDocName As String
   Dim subDocPath As String
   
   subDocPath = currPath & "\" & dirName & "\"
   
   ChangeFileOpenDirectory path:=subDocPath
   For i = 1 To filesToCopy.count
       subDocName = filesToCopy(i)
       masterDocRange.Subdocuments.AddFromFile name:=subDocName,
ConfirmConversions:=False, ReadOnly:=False, Revert:=True
   Next i
 
   masterDoc.Close
   
End Sub

It it the last for loop that is the problem. As soon as I try to add a sub
document. Word hangs and stops responding and I have to kill it from the task
manager.

Does anyone have any ideas why this does not work or this a bug in word?

I think I am going to use the INCLUDETEXT field instead. But I can't help
wondering what is wrong with my code.
