Microsoft has learned a few things in the last couple of years and one of those is was always a pain to view file extension and hidden files in the previous version of Windows. In order to avoid confusion regarding your saved files, you may want to configure Windows to show all common file extensions, such as .bat, zip, etc. Luckily, in Windows 10, Microsoft has made it really easy to show file extension and to show hidden files.
There are several methods to show the hidden files and file extension. But here, I will show you the simple steps to complete this task more easily.
Show File Extension in Windows 10 Explorer
On the right side of the View ribbon, you will see the Show/Hide panel. Here you can simply check the file name extensions box to show the file extension.
If you want to see all the hidden files including protected system files, you have to click on the Options button and click on the Change folder and screech option.
Then click on the View tab and scroll down to the Hide protected operating system files and uncheck the box. You will get a warning pop up message saying it could be unsafe to unhide protected files.
