Having trouble reading OS Open Names. This product is supplied as multiple (headerless) CSVs packed into multiple sets of zipped folders. I want to create a single reader and assign column names.

Typical zip file name ... "opname_csv_nz.zip" ... within each zipped folder the data files I'm after live in a sub-folder called DATA all with names of the form AANN.csv

 

 

Confusingly/annoyingly there is also another sub-folder called DOC which contains CSV files I don't want.

 

 

 

So what I want the reader to do is delve into each of the ZIP folders (there are 9), dig down into the DATA folder in each case and suck out all the CSVs (up to 25 in each DATA folder) and spit them out into a single data stream.

Hi,

 

 

I suppose that the zip contains hierachy foloder structure, but is not recursively zipped.

 

If my understanding is right, this Dataset setting might help you.
