Turning off the "Create PDF Compatible File" option really does the trick. I took a 54.4 MB file (heavy with photos) down to a paltry 1.4 MB. Thanks for the excellent time and memory saver.There's a discussion about this on Adobe's forums -- basically, AI wants to save files as PDFs, and throws a bunch of stuff in there (preview) -- turn this off and the file sizes are much smaller, and save quicker, too. I'm away from my computer right now else I'd find the discussion. Cheers!
