When you perform a certain task in Linux Mint, you will notice that the same program always tends to handle a particular task. For instance, when you play a music file, Banshee always launches, opening an image file brings up Image Viewer, and clicking on a Mail To link on a webpage opens up Thunderbird Mail. These are the “default programs” – programs that Linux Mint always accesses when you open up a particular kind of file or perform a certain task. However, if you have more than one kind of program capable of handling a specific task, you might want to assign a different program as the default. For instance, if you install the Opera web browser, you might want to make that the default instead of Mozilla Firefox.
To change the default programs, first launch the System Settings utility by going to the mintmenu, searching for “System Settings”, and then clicking on its icon when it appears in the search results. After System Settings launches, click on the Preferred Applications item in the fourth row. After the Preferred Applications item opens, you will then see a list of application types – Web, Mail, Calendar, and so forth. Click on the drop-down menu next to each item to set the default application for that task for type of file.
Once you are finished, close System Preferences, and Linux Mint will use the new default program settings.
