How to Show or Hide File Name Extensions on Windows 10 / 8 / 7?

Extensions tell your computer which application created or may open the file, as well as which icon to use. The docx extension, for example, informs your computer that Microsoft Word can open the file and displays a Word icon when you view it in File Explorer. With the default setup, all Windows versions, including Windows 7, 8, and 10, do not display file name extensions for known file types. In other words, if a file type is linked to a legal software, Windows will display merely the file name rather than its extension. There is nothing wrong with this, but it can cause unnecessary confusion when two files with the same name are available in a single folder. When troubleshooting your Windows, it may be required to see hidden file extensions.
