/**
 * Exception thrown when a requested operation is not allowed or possible on a directory
 * or file that should already exist. This type of error typically causes a 550 reply
 * code from an FTP server. Causes include:
 * <ul>
 *   <li>The file/directory does not exist</li>
 *   <li>The existing file/directory does not meet some required condition. e.g., trying to remove a non-empty directory</li>
 *   <li>The specified path is expected to be a file, but actually specifies an existing directory, or vice versa</li>
 * </ul>
