Does this need any action in PySpark?
How about importing using the shutil package?

This says "Binary file data source does not support writing a DataFrame
back to the original files." which I take to mean this isn't possible...
I haven't done this, but going from the docs, it would be:
spark.read.format("binaryFile").option("pathGlobFilter",
"*.png").load("/path/to/data").write.format("binaryFile").save("/new/path/to/data")
Looking at the DataFrameWriter code on master branch
<https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/DataFrameWriter.scala>
for DataFrameWriter, let's see if there is a binaryFile format option...
At this point I get lost. I can't figure out how this works either, but
hopefully I have helped define the problem. The format() method of
DataFrameWriter isn't documented
<https://spark.apache.org/docs/3.1.3/api/java/org/apache/spark/sql/DataFrameWriter.html#format-java.lang.String->
