====Concept of "Document-Centric"====
To The term "document-centric" has been used for a number of years. This term means that the focus is on the file, and is the task of the operating system to determine and launch the application that created the document so it can be automatically loaded for the user to edit. Other terms are also related to this term including ''"File Association"''. The major purpose is to provide convenience for the user, and to help increase their productivity by double-clicking on the file icon to edit a file, as opposed to launching the application, and manually loading the document into that application. Sometimes there are documents that can be edited or used by several applications. For example, a graphic file can be completedboth edited and viewed.'''If the user does not want the default application to launch and load in a document, they can right-click and select "Open with Other Application"'''.Then they simply select the application that will launch (in this single instance), and load in that document.
