One way to classify a file is on the basis of its domain. A file can be
permanent or temporary, or it may exist only to one particular process. The
file system maintains separate directories to record the location of temporary
files and permanent files. Of course, there is no file system directory for
files that exist only to their creating process (new files).
In this chapter, we will address the following questions:
What do the various domains mean?
Can a file's domain be changed?
How can the files in various domains be listed?
