Abstract
An operating system for managing a file system having a hierarchical structure stores a directory immediately before a file, when it is opened, to correspond with a file descriptor. When a task specifies the file descriptor, the directory stored to correspond with that file descriptor is presented to the task. The task reads stored information from the directory to detect the file name.
