Using Windows
(rename-file "C:/Lispcode/foo" "C:/Lispcode/bar")
where foo is a subdirectory of Lispcode
Lispworks allows one to rename the directory using RENAME-FILE as
above.
Allegro does not; RENAME-FILE tells you that the file FOO does not
exist. (nor does including a terminating '/' work). The only way
to rename a directory is to use implementation-specific EXCL:
functions to copy the directory and then delete the old one.
Corman Lisp doesn't have a RENAME-FILE function.

Are you sure the file that holds the directory is not _actually_ called
something else? foo.dir or something? As far as I know, it is fairly
unique to Unix to have directories that are available in the file system
as files with exactly the same name as the directory. But I have made it
a point of personal pride not to be infected by STDs or Microsoft.

The Windows API function 'MoveFile' works fine to rename a directory
when you give it the name as shown by a directory listing.
So if it is 'really' called something else the OS is doing a pretty
good job of hiding that fact.
