90 Part II: Preparing and Producing Professional Results<br />
Benefits of XML<br />
The <strong>Microsoft</strong> <strong>Office</strong> system uses <strong>Microsoft</strong> <strong>Office</strong> Open XML format as the default<br />
format for all applications. Files saved in <strong>Office</strong> PowerPoint <strong>2007</strong> are assigned the .pptx<br />
file extension. Saving a file in XML offers a number of benefits for users. <strong>First</strong>, XML<br />
enables you to separate data and formatting so that information you create in one<br />
application can easily be used in other forms. Secondly, XML files are much smaller<br />
than traditional files—especially when it comes to the graphics-intensive files that <strong>Office</strong><br />
PowerPoint creates—so the new <strong>Office</strong> PowerPoint <strong>2007</strong> files are much smaller, easier to<br />
download, manage, and share.<br />
Improvements for Team Presentations<br />
Today’s workforce is becoming increasingly mobile. We’re no longer tied to our desks (or,<br />
at least, not for long!) when we need to finish a project or finalize a presentation for review.<br />
<strong>Office</strong> PowerPoint <strong>2007</strong> offers several different ways you and your team members can continue<br />
to work on presentations, whether you are all working in the same office or on different<br />
continents.<br />
Enhancements in Shared Workspace Technology<br />
The previous version of <strong>Office</strong> PowerPoint included support for shared documents—so if your<br />
company is using <strong>Microsoft</strong> <strong>Office</strong> SharePoint technologies, you can create a shared document<br />
workspace where your presentations can be stored and shared among coworkers. <strong>Microsoft</strong>®<br />
<strong>Office</strong> SharePoint® Server <strong>2007</strong> is supported in <strong>Office</strong> PowerPoint <strong>2007</strong>, which gives you<br />
access to new features, including the project workflow and approval process. If you are routing<br />
your presentation for review to a number of members on your team, you can use the workflow<br />
process to create a task list for team members with automatic alerts to let them know when the<br />
presentation has been updated in the server space and is ready for review.
