Use head/tail/dd to extract the small part of the file you want
to edit, edit that small file, then use cat/head/tail/dd to put
it back into your original file.

Let's say you want to edit the last line of the file 208MB, which
is 1 million lines long:

tail -1 208MB > foo
emacs foo
(head -999999 208MB; cat foo) > new-208MB
