Large word file won't open

[zephyrprimo]

I have a 1 WORD file of about 1.2 GB. It doesn't open - I get an error message that 512 MB is the limit. Is there ANY way I can open the file using WORD, or anyway that I can partition the WORD file into smaller files?? Or any other way? I downloaded OpenOffice hoping that would work but it won't open a file this big. I have some charts within which are JPG images (accounting for the size) that it will be very difficult to lose!
