I use PowerPoint 2002 and when I use the program to open my PPt folder that contains 15 presentations, only 10 of the presentations appear. However, when I go the My Computer route and open the folder, all 15 presentations appear. Thirteen of the 15 presentations were created by me using my PowerPoint 2002. I have no idea what version created the other two presentations but they are among the five that do not appear when I open the folder using PowerPoint 2002. Any ideas about why the other five presentations do not open? Thanks.
