How do I show hidden extensions?

To show hidden file extensions in Windows, you simply need to adjust a setting within File Explorer. This allows you to see the full file name, including the characters after the last dot (e.g., .txt, .docx, .jpg), which denote the file type.

Steps to Show File Name Extensions

Enabling file name extensions is a quick process that can be done through the File Explorer interface. This setting helps users identify file types at a glance and enhances security by revealing potentially misleading file names.

Here's how to show hidden file extensions:

1. Open File Explorer:

   • In the search box on the taskbar, type file explorer.
   • From the search results, select File Explorer to open it.

2. Navigate to the View Tab:

   • Once File Explorer is open, look for the menu tabs at the top of the window.
   • Click on the View tab.

3. Enable File Name Extensions:

   • Within the View tab, locate the Show/hide group.
   • Inside this group, find the File name extensions check box.
   • Select (check) this box.

Once checked, file extensions will immediately become visible for all files in all folders opened via File Explorer.

Why Show File Extensions?

Showing file extensions offers several practical benefits for both general users and those with more technical needs:

• Accurate Identification: Easily determine the true file type (e.g., .pdf for documents, .mp3 for audio, .exe for executable programs).
• Security: Helps identify potentially malicious files that might try to disguise themselves (e.g., a file named image.jpg.exe would clearly show its true executable nature).
• File Renaming: When renaming files, you can ensure you don't accidentally remove or alter the extension, which could render the file unusable.
• Troubleshooting: Essential for developers and power users to work with specific file types and debug issues.
