A PPS file is a Powerpoint Slide Show, so a PowerPoint slideshow. The PPS format is the standard presentation format of Microsoft PowerPoint version 97 - 2003. With the 2007 version, Microsoft has introduced the new ppsx format. Of course you can also read PPS files with the new program versions.
Just like a ppt file, a PPS file contains slides that contain images, text, animation, and audio, among other things. A PPS file differs mainly in two things from ppt. On the one hand, it is not editable and on the other hand, if a program for displaying PowerPoint files is installed, the slideshow starts immediately.
This makes the PPS format ideal for presentations. In addition, there are converters that can convert PPS files into a executable (.Exe) file or various movie formats, such as Flash, avi or MP4. These files can then be started immediately and do not require an installed PowerPoint program. For the film formats, of course, a player is required. In general, all programs that can read ppt files can also handle PPS files.
Most often resolving problems with opening PPS files is very simple. Just install an appropriate program that supports such files. All of the listed programs support PPS files, but may vary in offered function and purpose. Some programs may be capable only of viewing contents of PPS files or offer file conversion options, but may not be capable of editing such files.
It is possible that although a compatible program has been installed on user’s system, it is not used by the system to open it. This may happen because no default application was associated with this type of files. To associate PPS files with given application, select "Open with" from drop-down menu (accessed by right-clicking on the file). Then select from the list the program or application you want to be used to open this type of file. If the PowerPoint applications is not on the list, select "Browse" option in order to manually locate the directory where PowerPoint has been installed.
Sometimes problems with opening PPS files may not lie with the application itself, but can arise due to other causes, such as:
