You have many options from which to choose in the Open dialog box. If necessary, click the Look in drop-down arrow and select a folder from the list. To move up a folder level, click the Up One Level button on the Open dialog box's toolbar.
TIP
Viewing Multiple Workbooks
Instead of constantly switching between workbooks, you can simultaneously view multiple workbooks onscreen in Excel. Select Window, Arrange to open the Arrange Windows dialog box. Then, select how you want the windows arranged (for example, Horizontal) and click OK. Click the title bar or in the body of the workbook in which you want to work to make it the active one (the active workbook is the one that displays a darker title bar); the active cell is then visible in the active workbook. To return to viewing only one workbook, double-click its title bar.
