PPT is the abbreviation of Power Point, remember that this is just an abbreviation and not an abbreviation.
The software Power Point is one of the Microsoft Office components produced by Microsoft Corporation, and the well-known Word and excel are also one of them.
Microsoft Office PowerPoint is a presentation graphics program, PowerPoint is a powerful presentation production software, also known as a slideshow by many people.
The difference between it and other components is that it enhances the multimedia support function, which means that its realization form is very different from others.
What I want to talk about today is: the difference between the suffix name of the PPT file, that is, the difference in the file saving format.
Over the years, new versions have been continuously launched. From 2003 to 2019, while improving the user interface and gradually improving the functionality, the saved format has also been upgraded. The presentations we see are usually divided into two parts. Two formats: ".ppt" and ".pptx".
The ".ppt" file format is a file generated by Power Point in the 2003 version, and the three letters in front, middle and last of Power Point are directly extracted to become the suffix.
At the beginning of file naming, Microsoft still followed the rules, that is, the suffix name cannot exceed 3 letters, and the file name cannot exceed 8 letters, which is no longer used now.
".pptx" is a file generated by power point in office 2007 and above, and can only be opened by PPT2007 and above, and has new slide effects.
The ".ppt" format is generated by versions before 2003. It is a format compatible with any version of PowerPoint and can be opened, but many new special effects do not support it.
So when you save in different versions of different software, you must remember to check the format of the saved file, otherwise you will not be able to use it in severe cases.
