Ubuntu Linux is a free, open source operating system. Like other operating systems, Ubuntu Linux has file associations that are user-configurable. When you double-click a file in Ubuntu's file browser or on its desktop, the file launches in the default program. For example, when you double-click an image file, it launches in the default image viewer. You can change the default program files launch in by changing the file association's in the "Properties" dialogue for a file of that type.
