Introduction

Showcasing file extensions in Windows 10 can be a helpful feature for both novice and experienced users. By enabling file extensions, you can easily identify the file type without having to rely solely on the file icon. This article will guide you through the process of showing file extensions in Windows 10, allowing you to have better control and understanding of your files.

Why Show File Extensions?

File extensions are the characters that follow the dot in a file's name, such as .txt, .docx, or .jpg. These extensions determine the file type and the default program associated with it. Sometimes, files with malicious intent may have misleading icons to trick users into opening them. By enabling file extensions, you can easily distinguish between legitimate file types and potentially harmful ones. Additionally, file extensions can help you troubleshoot issues, understand compatibility, and organize your files more effectively.

In Windows 10, the file extensions are hidden by default. This decision was made to create a cleaner user interface and avoid confusion for casual users. However, advanced users or those who deal with specific file types frequently may prefer to have file extensions always visible. Thankfully, Windows 10 provides several methods to show file extensions, allowing you to customize your file viewing experience.

In this guide, we will explore different methods to show file extensions in Windows 10, ranging from simple steps through File Explorer settings to using the Command Prompt. Whether you are a novice or an expert, you will find a method suitable for your needs and proficiency level.

Method 1: Folder Options

The most straightforward method to show file extensions in Windows 10 is by accessing the Folder Options settings. Here's how you can do it:

Open File Explorer by right-clicking the Start button and selecting "File Explorer" or by pressing Windows key + E.
Click on the "View" tab in the File Explorer ribbon at the top.
In the "View" tab, find and click on the "Options" button in the "Show/Hide" group.
A window titled "Folder Options" will appear. Select the "View" tab in this window.

Step	Description	Visual
Step 1	Open File Explorer
Step 2	Click on "View" tab
Step 3	Click on "Options" button
Step 4	Select "View" tab in "Folder Options" window

Once you are in the "Folder Options" window, scroll down until you locate the "Hide extensions for known file types" option. Uncheck this option to show file extensions. Click on the "Apply" button, followed by "OK" to save your changes. Now, file extensions will be visible in File Explorer.

If you are dealing with specific files types frequently and would like to modify the default program associated with them, you can use the "File Types" tab in "Folder Options." This tab allows you to choose the default program for specific file extensions and manage their behavior. However, it is important to exercise caution when modifying these settings, as it can affect how files are opened and processed by your computer.

Using the Folder Options method is the simplest way to show file extensions in Windows 10 and is suitable for most users.

Method 2: Registry Editor

If you prefer delving into the inner workings of Windows, the Registry Editor method provides a more advanced and customizable way to show file extensions. Here's how you can use the Registry Editor:

Caution: Editing the registry can have serious consequences if not done correctly. It is recommended to create a backup of your registry or system restore point before proceeding.

Open the Run dialog by pressing Windows key + R.
Type "regedit" in the Run dialog without the quotes and press Enter. This will open the Registry Editor.

In the Registry Editor, navigate to the following path:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced

On the right pane, locate the "HideFileExt" value. Double-click on it to modify.
Change the value data from 1 to 0. If the "HideFileExt" value does not exist, you can create it by right-clicking on the right pane and selecting "New" > "DWORD (32-bit) Value." Name it "HideFileExt" and set the value data to 0.
Click "OK" to save the changes.
Close the Registry Editor and restart your computer. Upon reboot, file extensions will be visible.

The Registry Editor method allows you to have granular control over various Windows settings, including file extensions display. However, it is recommended to proceed with caution and only make changes if you are comfortable working with the registry.

Method 2.1: Group Policy Editor

If you are using a Windows 10 edition that includes Group Policy Editor, you can use it as an alternate method to show file extensions. Here's how:

Open the Run dialog by pressing Windows key + R.
Type "gpedit.msc" in the Run dialog without the quotes and press Enter. This will open the Group Policy Editor.

In the Group Policy Editor, navigate to the following path:

User Configuration > Administrative Templates > Windows Components > File Explorer

Double-click on the "Hide extensions for known file types" policy on the right pane.
In the policy settings window, select "Disabled" and click "Apply" followed by "OK."
Close the Group Policy Editor and restart your computer. Upon reboot, file extensions will be visible.

The Group Policy Editor is only available in specific editions of Windows 10, such as the Pro, Enterprise, or Education editions. If you are using a different edition, you can skip this method and proceed with the other options.

Method 2.2: Command Prompt

If you are comfortable working in the Command Prompt, you can also use it to enable file extensions on Windows 10. Here's how:

Open the Command Prompt by pressing Windows key + X and selecting "Command Prompt" or "Command Prompt (Admin)" from the menu.

Type the following command and press Enter:

reg add HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced /v HideFileExt /t REG_DWORD /d 0 /f

Close the Command Prompt. You do not need to restart your computer for the changes to take effect.

The Command Prompt method is the fastest way to enable file extensions display and suitable for users comfortable with command-line interfaces.

Method 3: Windows PowerShell

Windows PowerShell is a powerful command-line tool that provides more advanced scripting capabilities compared to the Command Prompt. To show file extensions using Windows PowerShell, follow these steps:

Open the Windows PowerShell by pressing Windows key + X and selecting "Windows PowerShell" or "Windows PowerShell (Admin)" from the menu.

Type the following command and press Enter:

Set-ItemProperty -Path "HKCU:\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced" -Name "HideFileExt" -Value 0

Close Windows PowerShell. You do not need to restart your computer for the changes to take effect.

The Windows PowerShell method is similar to using the Command Prompt but offers additional functionality for scripting and automation purposes.

Method 4: File Explorer Options

If you prefer a direct method without navigating through menus or using the command line, Windows 10 provides the option to show file extensions through the File Explorer Options. Here's how:

Open the File Explorer by right-clicking the Start button and selecting "File Explorer" or by pressing Windows key + E.
In the File Explorer window, click on the "View" tab at the top.
In the "Show/Hide" group, check the box next to "File name extensions."
