Reason #2389 to buy a Mac: Smaller PPT files

I never thought that I would promote a Microsoft product as a benefit to use a Mac, but here goes:
A graphics-heavy PowerPoint file could actually use less disk space on a Mac!
I was working on a presentation at home on my iMac and the file came to a hefty 4MB. But when I re-saved the file in Windows -- even after compressing all of the images to be optimised for the screen, the file size weighed in at a whopping 8MB!

I saved half the disk space on a Mac!

This was admittedly a non-scientific observation. But still, saving 50% of disk space is quite a significant difference. Truly, the Mac business unit at Microsoft has churned out the best version of Microsoft Office.

Try copying it back to Windows and see how big it is.

I have long observed (repeatedly since 1998) that MS Word, Ppt and Excel document sizes are not correlated with the content. I have added in data and yet seen the file size shrink, sometimes by more than 10%.

It makes you wonder what on earth MS puts into the saved data.

You mean copy all of the content into a new Windows-based PPT file? Hmm, didn't think of that, will have to try it.

yyxgno need so much effort .. just re-save it in windows and see if it makes a consistent difference to the size. i think the variance is greater with graphics-heavy files.

Well, it turns out that no matter what I do in Windows -- re-saving, copying-and-pasting into a new file, make no changes and save -- the file size always increases by almost 2x.

Your PowerPoint logo doesn't load on my computer at home, but it does at work.
