File extensions help us to identify file types. The File Explorer in Windows 10 doesn’t show file type with file names with default File Explorer settings.
We here at IntoWindows recommend PC users to make Windows 10 always show file extensions with file names in File Explorer so that you can identify file types with ease. We also recommend you check extensions of files downloaded from the internet to avoid running malicious programs.
Of course, you can know the type of a file by looking its file icon if a program is associated to that file type.
You can also see the extension of a file by right-clicking on it and then clicking properties option. But making the File Explorer always to show file extensions is a wise idea to check file types with a glance at the file name.
