I'd use a text editor rather than Word. One Windows, something like NTEmacs,
Textpad or Programmers' File Editor (free, shareware and free, respectively).
Eg. Textpad: Search|Goto|[line|column|page|byte|bookmark]
If you read it in as acsii, goto byte 1,600,000. The limit on file size is
just memory, so you can open a big file. You could also linewrap at, say,
100 characters and goto line 160,000.
For a more elegant solution I'd knock out a Perl script
