What You’ll Learn in This Hour

• Using the OpenFileDialog and SaveFileDialog controls

• Manipulating files with System.IO.File

It’s difficult to imagine any application other than a tiny utility program that doesn’t use the file system. In this hour, you’ll learn how to use controls to make it easy for a user to browse and select files. In addition, you’ll learn how to use the System.IO.File and System.IO.Directory objects to manipulate the file system more easily than you might think. Using these objects, you can delete files and directories, move them, rename them, and more. These objects are powerful, so remember: Play nice!
