Directories

The directory management utilities are:

• (current-directory) returns the current directory and (current-directory path) sets the current directory to path. This procedure is actually a parameter, as described in section 9.4.1.1.
• (current-drive) returns the current drive name under Windows. For other platforms, the exn:misc:unsupported exception is raised. The current drive is always the drive of the current directory.
• (directory-exists? path) returns #t if path refers to a directory, #f otherwise. Unlike other procedures that take a path argument, this procedure never raises the exn:i/o:filesystem exception.
• (make-directory path) creates a new directory with the pathname path. If the directory is created successfully, void is returned, otherwise the exn:i/o:filesystem exception is raised.
• (delete-directory path) deletes an existing directory with the pathname path. If the directory is created successfully, void is returned, otherwise the exn:i/o:filesystem exception is raised.
• (rename-file-or-directory old new), as described in the previous section, renames directories.
• (file-or-directory-modify-seconds path), as described in the previous section, gets directory dates.
• (file-or-directory-permissions path), as described in the previous section, gets directory permissions.
• (directory-list [path]) returns a list of all files and directories in the directory specified by path. If path is omitted, a list of files and directories in the current directory is returned.
• (filesystem-root-list) returns a list of all current root directories.
