I don't think that's going to work the way you want. For the document to
work properly it will probably need to be at the beginning of the large
file. When people start downloading files, normally they start at the begining.
so most likely by the time you cut them off they will have already obtained
the part you care about.

If you explain more about yoru theat model and the format of the document
people might be able to give you some reasonable suggestions.

To append a large file to the end of your document, you can use the cat
command. Something like:
cat docfile largefile > largedocfile

Editing the file may end up making it small again depending on the editor.
