Many programs offer internal tools for configuring file associations, but the Control Panel configures all file associations through a single Windows feature. The Control Panel can command programs that support multiple formats to open all applicable file types. A media player that currently opens only MP3 can become your default program for WAV files, while an image editor that currently opens only its own project files can become your default program for all photo viewing.
1. Right-click the lower left corner of the desktop and click "Control Panel" to open the Control Panel.
2. Click the "Programs" category and then click "Default Programs" to open the Default Programs screen.
3. Click "Set Your Default Programs" to display programs currently installed on your computer.
4. Click a program in the list and click "OK" to associate that program with all files that it can open.
