If you’re looking at the files on your Windows 10 computer and you can’t see the period and three-letter suffixes of the filenames (such as .txt and .doc and .jpg), don’t panic! Microsoft has been hiding file extensions since Windows Vista, But very important to see file extension to identify the type of file you are trying to open from a security point of view. Because, normally the viruses and other malware disguise their executables as documents or pictures. A user can, unknowingly, double-click and run the file expecting the file to open in its appropriate program. Instead, the executable could wreak havoc on the system. example, a virus called my-picture.jpg.exe will appear in the File Explorer as my-picture.jpg. And since a JPEG file isn’t inherently dangerous, an absent-minded user could easily open this file by accident. Therefore, when we set up a new Windows system we change the default to show file name extensions, because this way we always know what we’re dealing with. Fortunately, it’s easy to do and only takes a minute show file extensions. Here’s how it is done.
How to turn on file extensions in Windows 10 to know the exact type of files?
1- In the taskbar, click the File Explorer icon or Press Win+E on your keyboard.
2- Then select the View tab from the menu across the top.
3- On the right hand side of the View ribbon, you’ll see the Show/Hide panel. Now check “File Name Extensions” box. File Explorer will remember this setting until you disable it in the future.
Note: Checking File Extensions will show the file extensions while unchecking it will hide the extensions.
1- Open File Explorer, click the View tab and choose the Options button.
2- Click the “View” tab at the top of the Folder Options window.
Disable the “Hide extensions for known file types” checkbox under Advanced settings.
Click “OK” to change your settings. But it’s faster to quickly toggle file extensions on or off via the ribbon.
That’s all. Hope you find this helpful!
