No need to save your PowerPoint presentation as a show

Lifehacker shares this Office productivity tips:

Most people save them as a PowerPoint Presentation (PPT). A PPT shows the slides and the work that can be done on the presentation. By saving as a PPS (PowerPoint Show), when you double-click it, it will auto launch into the show mode.

However, you don't need to save your presentation as a PowerPoint Show (thus creating another file), just rename the file from ".ppt" to ".pps" and presto! it is a Show. The only difference between a Presentation and a Show is the different filename suffixes. Also, if someone hands you a .pps file, just rename it to .ppt and you can open and edit it normally.
