Hi, I am creating Excel spreadsheets dynamically on a Web server using System.IO.Packaging. It has been working great for some time. I have noticed that the Excel files were sometimes very large for the amount of content and I noticed that when I opened them up and saved them using Excel that the size was reduced dramatically. After looking at the individual files in the package I saw that the files in the ones created by my program had a compression ratio of "0 %."
How can I add the package parts compressed? I am using Visual Studio 2010, Framework 4.0.
Thanks,
Lloyd Carter
