Copying files on the same FTP Server

I have files in a directory on a remote FTP Server. I want to copy (NOT MOVE) the files from one directory to another directory on the server. I cannot find a way to do this. I can create the directory, but it will only allow move to move the files or copy the files from my local computer. I do not want to have to upload the files each time I need a copy. Any help would be greatly appreciated.

Copying files on a remote server is not supported by FTP . The best solution would be to get shell access to the server and "cp" the file.
