How To Show File Extensions in Windows

Any file from a computer has an extension, for example .rar, .zip, .txt, .xls, .jpg and so on. These file extensions are automatically created by the programs that generated those files and are useful because computers will know what kind of files are and how to open them.

Is possible that you do not see extensions of common files and this option can be set by default when you install a fresh operating system or accidentally change this setting and you don't know how to revert it.

I prefer to view all extensions for all files, to know with what kind of files i am dealing (text, images, video, executable etc.).

The main Windows setting that displays or not file types is named Hide extensions for known file types and this is the reason that you see or not those extensions. In this article you will see how to show or display file extensions.
