File Types in Java:-

The File Types panel is broken into two areas:

File types. Cannot be changed or deleted from JBuilder, and they can be added only through the OpenTools API.

File Extensions. These are the extensions associated with the file types.

In the Figure (given below), each file type has an associated icon. This is the icon that will be used inside the Project pane to represent a file. These icons are extremely important, as icons are defined as the moniker for the tabs for the Content pane.

A question that usually arises is why does the AppBrowser need to support multiple file extensions for the same file. In the above Figure, the Archive file is selected on the top portion of the Dialog pane, and the associated extensions are listed on the bottom. One thing Java has been rather good at is using different file extensions to represent different functionality for the language, but all the types share a common underlying structure. The rar, war, zip, jar, and ear files are all basic files that implement the LZW compression algorithm but are used for different purposes within the Java language. An example of where additional file extensions may be added includes .bat/.cmd files in the Text File type.
