Workbench is the graphical file manager of AmigaOS developed by Commodore International for their Amiga line of computers. Workbench provides the user with a graphical interface to work with file systems and launch applications. It uses a workbench metaphor (in place of the more common desktop metaphor) for representing file system organisation.Confusingly, "Workbench" was also the name originally given to the entire Amiga operating system up until version 3.1.
