I am aware that the final section break contains data/coding that can be causing problems in a document, and have used a number of times the technique of copying a document, minus the final paragraph, to remove corruption. I leave to the experts what all is actually going on behind the scenes, other than section characteristics such as headers/footers, margins, etc.



Once or twice I have found that a corruption was present only in one section of a multi-new-page-section document. More usually, especially in very long such documents (more than 100 pages) in which the corruption is pervasive, I have taken the precaution of copying each section's contents, minus it's section break, separately, pasting into the new document and inserting new section breaks.

I am curious as to the difference between these intermediate breaks and the final one. Is my assumption correct that an intermediate one could be harboring the problem?
1. If so, could there be a solution to problems without having to copy the entire document over?
2. If not, is it correct to assume that copying the individual sections would make no difference to the result?
