How to Change Default Apps in Ubuntu
Default apps in Ubuntu control which program opens when you double-click a specific file type, such as launching a media player for video files or a browser for web links.
Ubuntu 22.04 LTS and newer releases let you change these default choices quickly through the main Settings menu so your preferred programs open every time.
Open System Settings, click Default Applications, and use the dropdown menus to select your preferred programs for various file types. Alternatively, right-click a file, select Properties, go to the Open With tab, choose an application, and click Set as default.
