File format facts for kids
A file format is like a special way a computer stores data in a computer file. Think of it as a unique container for different types of information. For example, pictures are stored in a different way than music files.
Every kind of data, like text, images, or sounds, can have many different file formats. Each format has its own special strengths and weaknesses.

What Are Different File Formats?
There are many ways to store information on a computer. For example, you can store text in more than five different ways. Two common text formats are the simple .txt format and the HTML format.
Simple Text Files (.txt)
A .txt file is very basic. It can only store plain letters, numbers, and symbols. It's like writing on a plain piece of paper without any special pens or colors.
Rich Text Files (HTML)
An HTML file is much more powerful. Besides text, it can also store links to other files. It can even remember how the text should look, such as if it's bold, italic, or underlined. This is like having a special notebook where you can add pictures, links, and change how your writing looks. HTML often works with another file type called CSS. CSS tells the computer exactly how to display the text, like what color it should be or how big.
Why File Formats Matter
Often, a file that can store more information (like an HTML file) will be larger than a file that only stores basic data (like a .txt file). Files with more features might also need a faster computer or more advanced programs to open and use them.
Open vs. Closed Formats
Some file formats are made by companies that create proprietary software. These formats are sometimes kept secret. This means that people who don't work for that company might find it hard to use their own files in that format without buying the company's software. This practice is sometimes called "vendor lock-in." It can make it difficult for people to choose different software programs because their files are tied to one specific company's product.
