The following article is a transcript from a our video product, "Intro to Powerpoint XP."
Before we end our discussion on PowerPoint images, I’d like to demonstrate how the addition of photos and graphics to our show can quickly bloat our presentation’s file size. Large files sizes can make your presentation unwieldy and potentially “un-sharable.”
Here’s what I mean:
When you save your presentation, PowerPoint saves your show into a self-contained
“.ppt” file on your computer’s hard-drive. This .ppt
(powerpoint) file contains,
embedded within it, everything you placed in your show, including:
(There are some things that are NOT included in your .ppt file, such as videos and sound, but we’ll ignore them for now. )
Normally, a simple PowerPoint file takes up very little hard-drive space. A 25-page presentation, complete with template and 25 pages of text, may only occupy 150k of space. That’s small enough to fit onto a floppy disk or email to a friend.
Add some pictures to your presentation, and everything changes! The same presentation, with only 10 photos on it, may result in a whooping 3,000k or 3 “meg” file! This PowerPoint file definitely won't fit on a floppy disk and shouldn’t be e-mailed (your friend’s ISP may not even allow attachments this large).
When you are giving presentation with many photos, it’s not uncommon to create very large presentations, sometimes 50 to 100 megabytes in size. Go right ahead, PowerPoint can handle those big shows. However, if you want to transfer or distribute copies of these big presentations, you’ll need to burn the .ppt file to a blank CD or use an external hard drive.
