Step-by-Step Guide to Show File Extensions in Windows

Initially, by default, the Windows operating system can hide file extensions for known file types to the user. To enable Windows to show the extension, there is a single procedure on every Windows computer; you type the following: It is specifically effective in identifying the difference between a particular type of file and improving the security aspect. Let us discuss why this setting is important and make it happen across different Windows versions.

Why Displaying File Extensions is Important

File extension plays an important role for the Windows platform in order for it to recognize files and open them via the right applications. These are appended to the filename, normally at three or four characters at most. For instance, a document created in Word will have an extension, either .docx or .doc. When it comes to audio, it will reach .mp3 or .wav. Image files could also contain .jpeg, .png, or .gif.

Reading the file extension is very helpful. You get to know the file type by its extension for your convenience and security purposes. For instance, viral programs normally copy themselves into the system, appearing like normal files. When there are no file extensions, a virus program called document.exe may look like a harmless PDF file. When the file extensions are conspicuous, it is quite easy to identify such frauds; therefore, the ability to prevent loading dangerous programs becomes within your reach.

Enabling File Extensions in Windows 11

Microsoft has also updated the Windows 11 File Explorer but has not hidden the way to disable showing file extensions. To activate this option, click on File Explorer and go to the top menu bar. Go back to the Menu bar, click View, then choose Show, and finally, select File Name Extensions. All files on your system will now show their extensions as soon as you press the combination that we discussed previously.

This simple modification guarantees that you can easily distinguish between file types and also boosts your efficiency in handling files. When viewing documents, media, or even executable files, this visibility can save you time and ensure peace of mind.

Enabling File Extensions in Windows 10

Using Windows 10 is just as easy as Linux if you would like to update to a newer version from the current version. Right-click on a space on the folder they have opened in File Explorer, and from the menu that appears, click on View. In the Show/Hide region, the check box labeled File Name Extensions is found. After enabling it, everyone can see the extension of the type of file selected.

It remains in this state until you choose to deactivate it. When you keep extensions viewable, you improve usability and increase the level of protection when working with files.

Enabling File Extensions in Windows 7

Users who are running Windows 7 have to dig deeper into the folder options to enable file extensions. To start the process, launch Windows Explorer and locate the Organize button on any toolbar. Then, the menu will drop down and let you go to Folder and search Options.

You do this by invoking the folder options window and changing the tab to view. In the next window, look for the option “Hide extensions for known file types” and remove the check mark from the left of the box. When you click OK on the folder options, every other file extension will be revealed system-wide.

Although slightly less conspicuous, this method is probably one of the most important for maintaining visibility and protecting files at work. The same Folder Options menu can be accessed in other Windows versions, but the switch, which is available in Windows 10 or 11, works faster.

Using the Registry Editor to Enable File Extensions

Another option is to use the Windows Registry, which is suitable for experienced users. This method works on all Windows versions, but it should be used carefully. The Registry is a very effective tool, but it might produce negative effects when it is altered inappropriately.

Firstly, bring up the Start Menu on your computer and then type in regedit, after which you will start the Registry Editor. Navigate to the following path:

Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced

Find HideFileExt in the list, right-click it, and change the value data to 0. Once you’ve done that, you need to reopen your File Explorer windows to see the extensions show up.

Although this method works the same as the options in File Explorer, it is recommended only if it is impossible to do it any other way or if you are comfortable working with the Registry.

Conclusion

Even if you are an average computer user, let alone an administrator who has to work with all sorts of files, turning on file extensions is an effective change. It makes it easy to know what type of file you are dealing with, it minimizes your chances of running a dangerous file extension, and it generally improves your interaction with Windows.

By making this adjustment, you’ll enjoy better organization, improved productivity, and greater security. So, take a few moments to enable file extensions and gain full control over your files—no matter which version of Windows you’re using.
