If you need to change a file extension on Windows 10, it’s a straightforward process. You’ll start by making file extensions visible in File Explorer. Then, you simply rename the file and change the extension. This allows files to be recognized correctly by various programs. Follow these steps for a smooth experience.
How to Change File Extension Windows 10
Changing a file extension in Windows 10 helps the operating system understand what program to use to open the file. Here’s a step-by-step guide to walk you through the process.
Step 1: Open File Explorer
Start by pressing the Windows key + E to open File Explorer.
File Explorer is your go-to hub for navigating files and folders on your computer. Think of it like a digital filing cabinet.
Step 2: Show File Extensions
Click on the ‘View’ tab at the top and check the box that says ‘File name extensions’.
This will make all file extensions visible. By default, Windows hides these to keep things looking clean, but you need to see them to change them.
Step 3: Find the File
Navigate to the file whose extension you want to change.
Use File Explorer to move through your folders. If you know where the file is, this should be a piece of cake. If not, use the search bar at the top right.
Step 4: Rename the File
Right-click on the file and select ‘Rename’. Change the file extension to the desired one (e.g., .txt to .jpg).
When you rename the file, make sure you only change the extension part. Windows will prompt you with a warning about changing the file type—click ‘Yes’ to proceed.
Step 5: Confirm the Change
Press Enter to finalize the name change. Confirm any prompts that appear.
Now, your file will have a new extension and should be recognized by a different program. If things go wrong, you can always change it back.
Once you’ve completed these steps, the file extension will be changed. This means the program that normally handles that type of file will now open it. For example, changing a .txt file to .jpg will make your image viewer try to open it.
Tips for Changing File Extension Windows 10
- Backup Your Files: Always make a copy of the file before changing the extension to avoid losing data.
- Know Your Extensions: Not all extensions are interchangeable. Make sure you know what the new extension does.
- Use the Right Programs: Some files need specific programs to open after the extension is changed.
- Beware of System Files: Changing extensions on system files can cause issues with your operating system.
- Check File Compatibility: Ensure the file content is compatible with the new extension; otherwise, it may not open correctly.
