How to Change File Associations in Windows 10

Changing file associations in Windows 10 is all about telling your computer which program to use when you open a specific file type. Whether it’s a PDF, JPEG, or MP3, you can choose your preferred app to handle each file. It’s a simple process: open the Settings app, navigate to Default Apps, and then select the desired file type and choose the app you want. Follow these steps to get it done quickly and easily.

Step-by-Step Tutorial to Change File Associations in Windows 10

Here’s a straightforward guide to changing file associations in Windows 10. Following these steps will help you set the right program for each of your file types.

Step 1: Open the Settings App

Click on the Start menu and select Settings (the gear icon).

The Settings app is your main hub for customizing Windows. Think of it as your computer’s control center.

Step 2: Navigate to Apps

In the Settings window, click on Apps.

You’ll find a variety of options here, but don’t get lost! We’re zeroing in on file associations.

Step 3: Select Default Apps

On the left-hand side, click on Default Apps.

This page allows you to choose which apps handle various tasks, including email, music, and more.

Step 4: Choose Default Apps by File Type

Scroll down and click on "Choose default apps by file type."

Here, you’ll see a long list of file extensions and the apps currently associated with each one.

Step 5: Change the File Association

Find the file type you want to change and click on the current app next to it. Choose your preferred app from the list.

Windows will present you with a list of compatible programs. Just pick the one you want, and you’re set!

After you complete these steps, Windows will remember your choice and use the selected app whenever you open that file type. It’s that simple!

Tips for Changing File Associations in Windows 10

  • Make backups of important files before changing associations, just in case.
  • Use the "Open With" menu to test different apps before making a permanent change.
  • If you install a new program, check if it automatically changes file associations.
  • Regularly review your file associations to ensure they match your preferences.
  • Restart your computer after making changes to ensure they take effect.

Frequently Asked Questions

No, it only changes which app is used to open them, not the files themselves.
