How to Choose a Default Application
A single file type can be opened by multiple applications. For example, PDFs can be opened by Adobe Reader, Microsoft Edge and Google Chrome just to name a few. The application that opens automatically when you double click a file is called your "default application".
To change your default application, type "default app" in the "type here to search box" > open "choose a default app for each type of file" from the suggestions > scroll to the file type you'd like to change > click the current application to display a list of suggestions and choose.
You can also open a file with a different application by right clicking the file > open with > choose from list of suggestions.
