The default file type is Single File Web Page when you save a presentation as a Web page in PowerPoint 2003

When you click File, and then click Save as Web Page to save a Microsoft Office PowerPoint 2003 presentation as a Web page, the default file type is Single File Web Page, and the default file name extension is .mht or .mhtml. You expect the default file type for a Web page to be an HTML file and the file name extension to be .htm or .html, as it is in PowerPoint 2002.

This behavior occurs because the MHTML format is the default file type for the Save as Web Page option in PowerPoint 2003.

To work around this behavior, use one of the following methods.

Method 1

1. On the Tools menu, click Options.
2. Click the General tab, click Web Options, and then click the Browsers tab.
3. Click to clear the Save new Web pages as Single File Web Pages check box.
4. Click OK two times.

Method 2

In the Save as type list, click Web Page (*.htm; *.html).

This behavior is by design.

If you plan to save most of your PowerPoint presentations as HTML files, you can change the default PowerPoint presentation file type to HTML with a file name extension of .htm. To do so, follow these steps:

1. Start PowerPoint 2003.
2. On the Tools menu, click Options.
3. On the Save tab, in the Save PowerPoint File as box, click Web Page, and then click OK.

After you change this setting, if you click Save As on the File menu, the default file type is Web Page (*.htm; *.html).
