also why doesn’t changing the file name from .pptx to .pdf work ?
In: Technology
The different file types are sort of like different languages. One program can understand how to read one file, but may not know how to read another file, even if they’re both pictures. If you want to program to be able to understand the file, you need to translate it to the format it’s familiar with. It’s sort of like having a book written in French. If you want an English speaker to be able to understand the book, you’ll need to translate it to English.
File extensions are just hints for program. If you have a pptx file, Powerpoint will look at that and say, “oh, I can open that.” But changing the extension doesn’t translate the whole file. It’s basically like taking book written in French and putting it in the English section of the library. English speakers will pick it up and try to read it, but they‘ll quickly realize they can’t understand it.
