Integrated file system concepts

 

This topic introduces the basic concepts of integrated file system, such as directory, link, path name, stream file, name continuity, extended attributes, and scanning support.

• Directory
  A directory is a special object that is used to locate objects by names that you specify. Each directory contains a list of objects that are attached to it. That list can include other directories.

• Link
  A link is a named connection between a directory and an object. A user or a program can tell the system where to find an object by specifying the name of a link to the object. A link can be used as a path name or as part of a path name.

• Path name
  A path name (also called a pathname on some systems) tells the system how to locate an object.

• Stream file
  A stream file is a randomly accessible sequence of bytes, with no further structure imposed by the system.

• Name continuity
  When you use the "root" (/), QOpenSys, and user-defined file systems, you can take advantage of system support that ensures characters in object names remain the same.

• Extended attributes
  An extended attribute is information associated with an object that provides additional details about the object. The extended attribute consists of a name, which is used to refer to it, and a value. The value can be text, binary data, or another type of data.

• Scanning support
  With the i5/OS operating system, you can scan integrated file system objects.
