Save and Save As Tabs of Backstage View in PowerPoint 2010 for Windows

When you click the File menu and access Backstage view in PowerPoint 2010 for Windows, you are presented with several options. On this page, we explore two of those options, as shown in Figure 1, below:

Save
Save As

The Save option works differently depending upon whether you are working with a new presentation or a presentation that has already been saved earlier:

1. When you choose File | Save option for a hitherto unsaved presentation, it opens the Save As dialog box, as shown in Figure 2, below. Here, you can provide a name for your presentation and choose a save location. In addition, you can also opt to save as different file types that PowerPoint supports. The default File save type is PPTX (PowerPoint Presentation) but there are several other formats you can choose.

2. When you select the File | Save option for a file that has been previously saved, you'll not be presented with any dialog box. Instead, PowerPoint overwrites your old file with any new changes made since the last save.

File Location for Save

Options for choosing a location, providing a file name, and selecting a file type are provided only when you save the newly created presentation for the first time. Thereafter, the Save option just saves all changes made since the presentation was saved last. If you want to save as a new file, choose the Save As option that we'll discuss next.
3. When you choose File | Save As for a presentation that has been saved hitherto or not, you always end up summoning the Save As dialog box that we looked at in Figure 2, shown previously on this page.
