When you click the File menu and access Backstage view in PowerPoint 2010, you are presented with several options. On this page, we explore three of those options (see Figure 1):

• Open
• Close
• Exit

Open

Follow these steps to open an existing file on your computer in PowerPoint 2010:

1. Access the File menu, and choose the Open option (see Figure 1).

2. This brings up the Open dialog box, as shown in Figure 2. Navigate to wherever your presentation files are saved, and you can open any of them. You'll find that PowerPoint can open files of various formats (types).

3. Select the presentation or file you want to open, and then click the Open button. Remember that the Open button has a downward pointing arrow next to it that provides more Open options (see Figure 3). Choose any of them -- an explanation of these options follows.

Here's a brief explanation of these options:


• Open, the default option is the same as clicking the Open button.
  
  
• Open Read-Only lets you open a read-only copy of the presentation -- this is great if you don't want to make some changes and overwrite the original presentation.
  
  
• Open as Copy lets you open a copy of the presentation -- almost like creating a new presentation while leaving the original unaltered.
  
  
• Open in Browser works only with certain file formats, such as MHT -- see file formats PowerPoint can open.
  
  
• Open in Protected View lets you open a presentation with restrictions to protect damage to your computer. You can open potentially dangerous files, such as those downloaded from an unknown source on the Internet in the Protected View.
  
  
• Open and Repair allows PowerPoint to attempt repair of a file that is possibly corrupt.

Close and Exit

The Close option is used to close the active presentation. PowerPoint prompts you to save any unsaved changes.

The Exit option allows you to exit the program. If you have one or more presentations open without unsaved changes, you are prompted to save before the program exits.
