The computer hardware industry is being updated for 40 years and there are numerous operating systems like Unix, Windows, DOS and many more. All of these systems have their own file extensions. Digital Equipment Corporation was the first one to implement file extensions. This occurred in the year of 1960. This was used by Microsoft DOS systems and then by the Windows systems. Generally the file extensions were denoted by the base name and the other word was attached to it separated by a full stop. But operating systems like Mac and Unix never used the file extensions. There are thousands of different programs run by these systems and each one of them features a different file extension. If you would like to know more about these file extensions, you can refer to any online library as they have archives full of important information on file extension.

Sometimes you might have problem with the pps files like the windows suddenly cannot open them. The error message states that the required programs are not found. The cause of this problem with the file extension pps might happen because the windows system is facing some sort of registration problem. The pps extensions are used with the power point presentation files. Hence the necessary program to open it is Power Point. Sometimes Staroffice or OpenOffice are used to open it. If you have an outdated power point program, similar error messages can show up. So file extensions are one of the commonest programs we use and you can update them using various programs.
