About hyperlinks and action buttons

Microsoft Office PowerPoint 2003

When you create a presentation with links to several files, it is a good practice to put the files in a common location on a server and set a hyperlink base. If the server URL changes, you only have to update the hyperlink base, not the paths to the hyperlink destinations.

ShowTesting and repairing broken hyperlinks

Before you give a presentation, you should always check for broken hyperlinks and test hyperlinks to external destinations. A broken hyperlink is one that has an invalid destination— when the hyperlink is clicked, PowerPoint or the Web browser displays an error. The cause might be as simple as a URL that was mistyped, or a hyperlink to a destination that was moved or deleted.
