It's not the answer that I want to receive.

In your manual there is no chapter to notice that the file name must not have special character.

And my question is why the special character of file names and directory names are seen right in CFIS but not in FTP (or vice versa).

If I may be not wrong, Korean character problem is not the problem of special character but of 2 byte character. And I think that there is a bug or unsupportness of 2 byte characters in your program dealing with FTP of NFS.

Would you please give me some right answer?
