features in your presentation. Printed pages, overheads, and 35mm slides can
show only static content.
A presentation is to PowerPoint what a document is to Word or a worksheet
is to Excel. In other words, a presentation is a file that you create with
PowerPoint. Each presentation that you create is saved on your computer’s
hard drive as a separate file.
PowerPoint 2013 presentations have the special extension .pptx added
to the end of their filenames. For example, Sales Conference.pptx and
History Day.pptx are both valid PowerPoint filenames. When you type
the filename for a new PowerPoint file, you don’t have to type the .pptx
extension, because PowerPoint automatically adds the extension for you.
Windows may hide the .pptx extension, in which case a presentation file
named Conference.pptx often appears as just Conference.
I recommend you avoid the use of spaces and special characters, especially
percent signs (%), in your filenames. If you want the effect of a space in a
filename, use an underscore character instead. Spaces and percent signs in
filenames can cause all kinds of problems if you post your presentation files
to the Internet, either on a web page or even as a File Transfer Protocol (FTP)
Versions of PowerPoint prior to 2007 save presentations with the extension
.ppt instead of .pptx. The x at the end of the newer file extension denotes
that the new file format is based on an open XML standard data format that
makes it easier to exchange files among different programs. PowerPoint 2013
can still save files in the old .ppt format, but I recommend you do so only
if you need to share presentations with people who haven’t yet upgraded to
PowerPoint 2007 or later. (You can download a program called the Microsoft
Office Compatibility Pack from http://www.microsoft.com/en-us/
download/details.aspx?id=3 that enables PowerPoint 2002 or 2003 to
read and write files in .pptx format. This program enables you to share your
.pptx files with people who haven’t yet upgraded.)
PowerPoint is set up initially to save your presentation files in the Documents
folder, but you can store PowerPoint files in any folder of your choice on
your hard drive or on any other drive. You can also save your presentation
to online file storage, such as Microsoft’s SkyDrive. And, if you wish, you can
write a presentation to a USB flash drive or a writable CD or DVD disc.
What’s in a slide?
PowerPoint presentations comprise one or more slides. Each slide can
contain text, graphics, and other elements. A number of PowerPoint features
work together to help you easily format attractive slides:
