If you want to hide or see a file extension on Windows 11, then take the help of the methods listed in this guide for ease.
Windows is a versatile operating system offering a lot of features. One such feature of the OS is the file extensions mode. Generally, by default, the system hides the file extension on your device. This is done by the developers to ensure that the user, unknowingly, may not change the file extension and later face problems in launching the files. Hence, you will see that on all the files present on your system, no extension is available by default as may be seen in other operating systems.
But, sometimes, you may want your system to show a file extension on your device. You may want to see the extension to know about the extension, rename the file extension, or any other purpose. This demand is quite common and made by over thousands of users online. With the help of this guide, we will help you with the same. But before we go over the methods, let’s have a look at why should you show a file extension right below.
Why Should You Enable the File Name Extensions on Your Windows Device?
Different kinds of images, audio files, video files, and other documents use different extensions to show their identities. This extension helps a lot when you do not have a default app to open the file and want to run the file with ease.
You can simply have a look at the name of the extension after viewing file extensions. This will allow you to know what kind of document is it and run the file accordingly. Additionally, you can google the extension to know about it and then analyze which tool is required to run the same.
Lastly, the best benefit of viewing file extensions is that you can analyze whether the file is the one you were looking for or just a scam. Let’s understand this with the help of an example.
Suppose you have saved a PDF document on your computer’s storage named ‘driving license’. Now, scammers and ransom handlers may also add a file to your store with the same name. The Windows OS generally uses the .exe extension for app files. The fake driving license file will contain the .exe extension instead of PDF. Your icon image may also be that of a PDF but still, the file extension is different. When you run the file supposing it is the original driving license that you were looking for, your files will be exposed to the meddlers and hackers.
Hence, you should always enable the option to show a file extension on Windows for better protection.
