How to Batch Change File Extensions in Windows 10
Need to change the file extensions of multiple files at once in Windows 10? It’s easier than you might think! First, you’ll need to make file extensions visible. Then, you can use File Explorer to batch rename your files. Let’s dive into the step-by-step process.
Step-by-Step Tutorial: How to Batch Change File Extensions in Windows 10
In this tutorial, we’ll show you how to change file extensions for multiple files at once. This can save you a lot of time, especially if you’re dealing with a large number of files.
Step 1: Open File Explorer
Open File Explorer by pressing the Windows key and ‘E’ on your keyboard.
File Explorer is the default file management application in Windows 10. It’s your gateway to accessing folders, files, and drives on your computer.
Step 2: Make File Extensions Visible
Click on the ‘View’ tab in the File Explorer ribbon, then check the box that says ‘File name extensions’.
By default, Windows hides file extensions. Enabling this view will allow you to see and edit the file extensions easily.
Step 3: Navigate to the Folder
Go to the folder containing the files you wish to change.
Ensure you are in the correct directory to avoid renaming the wrong files. Double-check the files’ names and extensions.
Step 4: Select the Files
Select all the files you want to change by holding down the ‘Ctrl’ key and clicking each file, or by pressing ‘Ctrl + A’ to select all files in the folder.
Selecting multiple files at once allows you to batch rename them, saving time compared to renaming each file individually.
Step 5: Rename the Files
Right-click one of the selected files, choose ‘Rename’, then change the extension of one file. Press ‘Enter’.
When you press ‘Enter’, all selected files should now have the same new extension. Be cautious, as this action changes the file types, which might make them unusable if not done correctly.
Step 6: Confirm the Change
A warning might pop up asking if you’re sure you want to change the file extensions. Click ‘Yes’ to confirm.
This is a safety feature in Windows, ensuring you understand that changing file extensions can affect how files are opened or used.
After you’ve completed these steps, all the selected files will have the new extension you specified. Be sure to verify that the changes did not corrupt any files, especially if working with sensitive data.
Tips for Batch Changing File Extensions in Windows 10
- Backup your files first: Always create a backup of your files before making bulk changes to avoid accidental data loss.
- Test with a few files: Try changing extensions on a few files first to ensure the process works without issues.
- Use the Command Prompt: For more advanced users, the Command Prompt can be used for batch renaming with more control and options.
- Watch out for file types: Ensure the new extension is appropriate for the file type to avoid making the files unusable.
- Undo if needed: If a mistake is made, you can rename the files back to their original extensions, but it’s easier if you have a backup.
