ANSI Common Lisp 20 Files
20.1 File System Concepts
This section describes the Common Lisp interface to file systems.
The model used by this interface assumes
that files are named by filenames,
that a filename can be represented by a pathname object,
and that given a pathname a stream can be constructed
that connects to a file whose filename it represents.
For information about opening and closing files,
and manipulating their contents, see Chapter 21 Streams.
The next figure lists some operators
that are applicable to files and directories.
