How to Make a power point presentation (.ppt) open directly as a slide show
It is always goood to have a power point presentation open directly as a slide show whenever you submit projects or when business meetings are held.To do this open the .ppt file in the corresponding software like ms office or open office and save it as a power point show file with an extension .pps. In Ms power point go to file> save as . Then select power point show(.PPS) rather than power point presentation (.ppt).
In Ms office 2007 and higher versions you can also save it as .ppsx or .pptx . However this file will not work in earlier version like office 2003.
