Make Windows Show File Extensions
By default, File Extensions are not visible on Windows 10 computer and also on computers running on older versions of Windows operating system. However, not being able to See File Extensions is a bad idea from security point of view, as you may be tricked into opening unsafe files on your computer. For example, you won’t be able to know whether a file named “document01” is a document file or a harmful executable file, without taking a look at its hidden extension part. Similarly, a file may look like a genuine PDF File with a PDF icon, but may turn out to be a harmful executable file with .exe Extension. Hence, it is recommended that you enable the option to Show File Extensions and minimize the chances of opening harmful executable files on your computer.
