Hm.. @dongjoon-hyun Do you mind if I ask a question?
If my understanding is correct, the `name` will be `part-..` file whether
the parent directory contains `_` or not. So, it would be unnecessary extra
checking. It is happening in `ParquetFileFormat` as well.
Do you mind if I open a follow-up to clean up those?
