Thank you very much for the answers.
The “R Script” has become the right solution for selecting files and reading two-level zips.
I take the list of files to be unpacked from a table with a loop.
This is works very vell.
However, there is a minor problem: my Zip files do not always contain all the files I give on the input. In this case, all the files in the ZIP will be extracted. The solution I think would be a “file exists” test, I tried to find a solution with the “TRY (Variable ports)” node, I don’t know if this is a good approach?
Thanks for the reply, I managed to try it. What I faced with the problem in this case was that the cycle ran very slowly. The data stream is managed from a network drive that probably caused the problem. The solution worked anyway.
Thanks for sharing a snapshot of the solution. It clearly shows the algorithm to follow.
Would it be possible to share the workflow too, just with the portion you have snapshotted? I believe other people in the forum would appreciate to have access to the R code solution too. Thanks in advance.
@palatisa I will have a look at it. The structure doe slook good. You could do two more things: give ist a title besides the echnical one with the _. That would look better if someone finds it. And maybe insert a link to this thread so people could see the context. You can edit the description of the workflow.
