@Nifi_Al Use getFile/putFile to read and write in your flow. Then If you use unpackContent against a zipped flowfile it should create individual artifacts flowfiles which can be additionally unzipped further. Alternatively, if you can create a script to unzip recursively, you can use nifi to executeScript. Maybe even use executeProcess too.

@Nifi_Al ,

Here's a way to do that:

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.
