•	/New - Displays a dialog box to specify a new address book file Example: Click Start, click Run, and type wab /new
•	File name - Opens the specified address book file Example: If your Windows Address Book is named Test.wab and is located in the C:\Program Files\Outlook Express folder, click Start, click Run and type: c:\program files\outlook express\test.wab
•	Folder name - Displays a dialog box to select an address book file from the specified folder Example: If your Windows Address Book is named Test.wab and is located in the C:\Program Files\Outlook Express folder, click Start, click Run, and type c:\program files\outlook express
