If you want to deliver more than one slide show at a time, you can create and use a playlist. A playlist is a simple text file than contains a list of presentation file names in the order that you want to deliver them. File names in a playlist file need to include the full path to the presentation unless they are located in the same location as the PowerPoint Viewer. It is not possible to add command-line switches to the presentation file name in the playlist.
Open a text editor, such as Notepad or WordPad.
Type the presentations files you want to use on separate lines.
If the presentation files are not in the same location as the Viewer, be sure to include full paths.
Save the text file with the name you want, such as playlistpres.txt, and then exit the program.
To avoid problems, place the text file, and presentation files in the same folder as the PowerPoint Viewer.
Click the Start button, and then click Run (XP), or point to All Programs, point to Accessories, and click Run (Vista).
Type "c:\path to folder\ PPTVIEW.EXE" /L "playlistpres.txt"
Quotation marks are required if there are spaces in the path or file name; they are optional when there are no spaces.
Click OK.
