>                 Key: ARROW-15280
>                 URL: https://issues.apache.org/jira/browse/ARROW-15280
>             Project: Apache Arrow
>          Issue Type: Improvement
>          Components: R
>    Affects Versions: 6.0.1
>            Reporter: Bob Rudis
>            Priority: Minor
>
> ARROW-4406 notes that:
> >Currently reading parquet files generated by Hadoop (EMR) from S3 fails with "ValueError: >Found files in an intermediate directory" because of the _$folder$ empty files.
> This was fixed in the pyarrow but R still has this issue.
> The R side does not seem to have something similar to:
> {{  def _should_silently_exclude(self, file_name):}}
> {{    return (file_name.endswith('.crc') or # Checksums}}
> {{            file_name.endswith('_$folder$') or # HDFS directories in S3}}
> {{            file_name.startswith('.') or # Hidden files starting with .}}
> {{            file_name.startswith('_') or # Hidden files starting with _}}
> {{            file_name in EXCLUDED_PARQUET_PATHS)}}
