Changing a file extension in Windows 10 is a straightforward task that can be done in just a few simple steps. By adjusting a file’s extension, you can change how Windows interprets and opens the file. This guide will walk you through the entire process, ensuring that you can easily change any file extension without causing harm to your files.
How to Change a File Extension in Windows 10
This step-by-step tutorial will show you how to change a file extension in Windows 10. These steps will help you navigate through the necessary settings and successfully change the extension of any file.
Step 1: Open File Explorer
Open File Explorer by clicking on the folder icon in the taskbar or by pressing the Windows key + E.
File Explorer is your main tool for navigating through files and folders on your computer. It’s the starting point for finding the file you want to change.
Step 2: Locate the File
Browse to the file you want to change the extension for, and click on it to select it.
Make sure the file is easily accessible. You might want to move it to a more convenient location like your desktop or a specific folder.
Step 3: Enable File Extensions
Click on the ‘View’ tab at the top of File Explorer, then check the box that says ‘File name extensions.’
This step is crucial because, without seeing the file extensions, you won’t be able to change them. It makes the extensions visible for all files in the directory.
Step 4: Rename the File
Right-click the file, select ‘Rename,’ and change the extension by typing the new one after the period.
Be cautious when renaming the file. Ensure you only change the extension part (the letters after the dot) and leave the main file name intact.
Step 5: Confirm the Change
Press ‘Enter’ after typing the new extension, and confirm the change when prompted by Windows.
Windows will warn you that changing the file extension might make the file unusable. If you are sure about the new extension, click ‘Yes’ to proceed.
After completing these steps, Windows will recognize the file with its new extension, and it will be associated with the new file type application.
Tips for Changing a File Extension in Windows 10
- Always make a backup of your file before changing the extension in case something goes wrong.
- Double-check the new extension to ensure it’s compatible with the file’s content.
- Use trusted file extensions that you know will work with the file type.
- Remember that changing a file extension does not convert the file format; it only changes how Windows treats the file.
- Be aware that some programs might not open files with altered extensions properly, leading to errors or data loss.
