How to Change Extension of a File in Windows 10: Step-by-Step Guide

Changing the extension of a file in Windows 10 is a straightforward process that can help you identify and open files with the appropriate programs. To change a file extension, you need to enable file extensions in File Explorer, rename the file, and then verify the change.

How to Change the Extension of a File in Windows 10

In this section, you will learn the detailed steps to change a file extension in Windows 10. These steps will guide you through enabling file extensions, renaming the file, and confirming the change.

Step 1: Open File Explorer

First step: Click on the File Explorer icon on your taskbar or press ‘Windows + E’ on your keyboard to open it.

File Explorer is the hub for all your files and folders in Windows 10. It’s where you’ll see your file extensions.

Step 2: Enable File Extensions

Second step: Click on the ‘View’ tab at the top of File Explorer and check the box labeled ‘File name extensions.’

By default, Windows hides file extensions. Enabling this option will show the extensions for all your files, which is crucial for renaming them.

Step 3: Locate the File

Third step: Navigate to the folder containing the file whose extension you want to change.

Make sure you know where the file is located so you can easily find and rename it.

Step 4: Rename the File

Fourth step: Right-click on the file, choose ‘Rename,’ and change the extension after the dot (e.g., from .txt to .pdf).

Renaming the file extension changes how Windows reads the file. It’s like giving your file a new identity.

Step 5: Confirm the Change

Fifth step: A warning message will pop up; click ‘Yes’ to confirm the change.

Windows will alert you that changing the extension might make the file unusable. This is a normal warning, and clicking ‘Yes’ allows the change to take effect.

After completing these steps, your file will have a new extension, and Windows will treat it accordingly. This might mean a different program will be used to open it, or it might change the file’s behavior.

Tips for Changing the Extension of a File in Windows 10

  • Always back up your files: Before changing the extension, make a copy of the original file in case something goes wrong.
  • Know the new extension: Make sure you understand what the new extension does and which programs can open it.
  • Be cautious: Some extensions are critical for the file to function properly. Changing them might render the file useless.
  • Use the correct format: Not all files can be changed simply by renaming. For example, a text file renamed as a PDF won’t magically become a formatted document.
  • File type icons: Icons may change, indicating whether the operating system recognizes the new extension.

Frequently Asked Questions

Can I change any file extension?

Yes, you can change any file extension, but it doesn’t mean the file format will change to fit the new extension. This could make the file unusable if the format and extension don’t match.

What are file extensions?

File extensions are the suffixes at the end of filenames (e.g., .txt, .jpg) that tell the operating system what kind of file it is and which programs can open it.

Will I lose my data if I change a file extension?

You won’t lose data by changing the extension, but the file might not open correctly if the extension doesn’t match the file format.

Why doesn’t my file open after changing the extension?

This usually happens because the file format does not match the new extension. Ensure the file type is compatible with the new extension.

How do I revert a file extension change?

Simply follow the same steps and rename the file back to its original extension.
