You can free up hard disk space by uninstalling the practice files that were installed from the companion CD. The uninstall process deletes any files that you created in the chapter-specific folders while working through the exercises. Follow these steps:
On the Windows taskbar, click the Start button, and then click Control Panel.
In Control Panel, under Programs, click the Uninstall a program task.
In the Programs and Features window, click Windows SharePoint Services 3.0 Step by Step, and then on the toolbar at the top of the window, click the Uninstall button.
If the Programs and Features message box asking you to confirm the deletion appears, click Yes.
