It is sometimes useful to consult the extension of a file before opening it, if only to know its type or to detect a questionable file downloaded from the Internet. By default, extensions are not necessarily displayed on Windows 10.
In this tutorial dedicated to teaching you how to organize your workstation on Windows 10, we explain how to display file extensions on Windows 10.
