This has been a recurring question in the Community forum. I replied to those a few times so I've decided to post the answer here as an article so that's easier to find and reference.

 

The question is: if you have a ZIP file that contains other ZIP files (which may in turn contain other ZIP files, etc.), how can I extract all the ZIP files, recursively, using NiFi?

 

One way to do that is to implement the following data flow:

The RouteOnAttribute processor checks the file name and if it's a ZIP file it sends it for unpacking. Otherwise sends the non-zip file downstream.

You can find the flow definition attached below.

@araujo It would be awesome if you could also link a flow definition file....

Good idea, @steven-matison .

I've attached the flow above.
