Create a directory on an SFTP server.
int MakeDirectory(const QString& qsNewDir);
A directory with path specified by NewDir is created on the SFTP server. NewDir is either an absolute path on the server, or a path relative to RemotePath.
If there is no SSH session in place, one is automatically created by the component first.
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
