| bDisableBackup | If true, existing files will not be backed up |
| bCreateWriterLazily | If true, delay the creation of the file until something needs to be written, otherwise, open it immediatedly. |
| FileOpenedCallback | If bound, invoked when the output file is successfully opened, passing the actual filename. |
