A text file is like a piece of paper that has words and sentences written on it. But instead of being on paper, it's on a computer. You can use a special program like Notepad or WordPad to open and read these text files. They don't have any fancy pictures or colors, just plain words that you can read. Text files are really useful for storing information that you want to read later or share with someone else. Think of it like a little book that holds all the words but none of the pictures that you can save on your computer!
