Up to speed with PowerPoint 2007

Some benefits of new file format

The format is part of the new Office Open XML Formats. It's based on the XML (Extensible Markup Language) programming language.

You don't have to understand XML — that's behind the scenes. Just know that the new format means improvements to PowerPoint. Here are its chief benefits:

Safer presentations     Presentations containing unwanted code, macros, or controls are easier to identify and block.

Reduced file size     Presentations are automatically compressed.

Improved information security     Personal and business-sensitive information is easier to remove.

Improved damaged-file recovery     A file can still be opened even if part of it is damaged.

Easier integration     Presentation content can be shared with and opened in other programs.
