Copies a folder.
int CopyFolder(const QString& qsid, const QString& qsdestFolderID);
This method copies a folder to a new parent folder. Please note that two folders with the same name may not exist under the same parent folder. Since this method does not change the name of a folder, it is not possible to directly create a copy of a folder in the original folders location.
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.)
