What are the popular file extensions kids should learn about?

A file extension is the suffix used at the end of a file name to show what type of computer file is being used. The suffix also implies what program can be used to read the content of the file. Here are the most popular file extensions that kids should learn about.


DOC and DOCX

Whether DOC or DOCX is used is simply dependent on the version of Microsoft Office being used. DOC and DOCX files can contain text, images, tables, and other elements. The file type is perfect for writing essays and presenting graphics. Once a DOC or DOCX file has been saved, users can easily edit it in a Word program.


PDF

However, unlike a DOC file that maintains formatting and can include pictorial elements, TXT documents solely contain raw text. A TXT file stores text and text only, meaning it has very limited flexibility. But when users need to securely store text data and share it, TXT can be a very useful file extension.


HTML


For students to fully understand HTML, they will need to . HTML is typically used for web pages. However, kids can save documents in the HTML format easily. Most every word processing system is able to format text into the HTML extension and such files can be opened with any browser.


PPT and PPTX

Those formants include text, images, tables, graphs, video files, audio files, and animations. Files saved with the PPT or PPTX extension can be opened by any other program besides PowerPoint, but in another program, the layout may differ from the original PowerPoint file.
