I have a big workbook. Since it takes so long to save a workbook when I only change 1-2 cells. If I split it up and link say, my input page (book1) to a huge database (book2), will have any errors later. I do have to forward this to several people now as a zip file. But if I separate and link to each other, I can send as individual files which they would like, but since they store them on their own pc....what would be any issues????

I guess my biggest fear is loosing the link from book to book2 during this process?
