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 Streams.

Figure 20-1 lists some operators that are applicable to files and directories.

  compile-file  file-length      open            
  delete-file   file-position    probe-file      
  directory     file-write-date  rename-file     
  file-author   load             with-open-file
