Office 2007 File Sizes

My company is planning to implement Office 2007 soon. One of the things I wonder about is the sizes of the various file formats. PowerPoint 2007 will create the legacy .ppt file format as well as the new .pptx file format.

I also get a lot of questions about PDF tools and have performed some PDF file size tests at home.

Today I had a moderate sized PowerPoint deck. It had some graphics in the template and lots of text boxes and maybe a table or two but no SmartArt or animation. It was less than 10 slides.

I had created it as a .pptx file. As I prepared to share it, I saved it as a PDF using Adobe Acrobat 6.0 (I know that's old but it still works). Then getting a wild hair, I also saved it as .ppt and Microsoft's .mdi and .xps formats.

.mdi is a "high resolution, tag-based graphics format. .MDI files are only supported by the Microsoft Office 2003 version."

.xps is Microsoft's new "XML Paper Specification." The wikipedia explanation is here.

Here're the results:
