As another example, with ADFS (Advanced Disk Filing System) on the Acorn/BBC computer family, the root directory was specified with `$`, and the directory separator was `.`.
ADFS is the filesystem, IDEDisc4 is the disc name, $ is the root directory, Games is a subdirectory, !Repton is an application directory (since it begins with !) and Arctic is a file within the application directory, not normally referenced by users.
