With FEXIST you still do not know if it is a file or directory . (in V6 ) I
try to open the directory with the DOPEN function. If it fails it is not a
directory or the dirname is incorrect:
rc=fileref('<fileref>','<dirname>')
dir_id=DOPEN('<dirname>')
if dir_id then {it exists} ELSE {not exist};
IF dir_id THEN dir_id=DCLOSE(dir_id);
rc=fileref('<fileref>','');


(same principle as the libname function)

Yes, use the FEXIST function.

  I know one way to check to see if a directory or
sub-directory in PC exists or not using LIBREF
function,
Are there any other easy ways or functions to find
that information?.

Using V8.1 on NT.
