DOS (Disk Operating System) is an operating system primarily used in the early days of personal computing to manage disk storage and file systems. It is known for its command-line interface and was widely used before the advent of graphical user interfaces.
A Folder is a digital metaphor used to organize files on a computer, similar to how physical folders organize documents in a file cabinet. Initially termed directories in DOS, the nomenclature was later adopted by Windows 95 and subsequent versions.
