He's tried chopping it up into smaller files and saving those, but whatever he does he gets the same error response. If David tries to save it without altering it, there is no error response, but it also appears that the document isn't really saved anew (insofar as its Date Modified property isn't updated). If he tries to edit it and save it, he always gets the reply that 'The disk is too full or too many files are open.' Neither situation is true. David has a large Word file, approximately 6.3 MB in size.
