How do I get a list of objects within a sub-directory on cloud storage using the Bigquery Java api?

I can get a list of objects within a folder but not within a second level folder. So if I have /Folder1/Folder2/File1.csv /Folder1/File2.csv

I can get Folder2 & File2.csv using the following command: 

list = cloudstorage.objects().list("Folder1");

But how do I get the list of objects within Folder2?

this doesn't seem like a 'bigquery' question? – Felipe Hoffa
@FelipeHoffa My bad, I added that I'm using the Bigquery Java API – Febian Shah
still not bigquery, I think you want the [google-cloud-storage] tag – Felipe Hoffa
I think you should use setPrefix method to filter results to objects whose names begin with this prefix. and Yes, this is not BigQuery but rather Cloud Storage JSON Java API – Mikhail Berlyant
Assuming your bucket is Folder1 i think the value to pass there - will be "Folder2/" – Mikhail Berlyant

I think - you should use setPrefix method to filter results to objects whose names begin with this prefix. Assuming your bucket is Folder1, you should try 

setPrefix("Folder2/")
