Locking paragraphes and rows

[ORendaVD]

Hello all,
I have a reaaly big .docx (1332 pages) and I need to make changes to
it, but every time I enter a paragraph or new line in page 4 (for
example) all the rows below it move downwards. how can I edit a page
without modifyng the entire .docx???

thank you.

What do you mean by rows? And how do you expect to enter more text and not
have everything belong it move down?
