How can I join and compress a list of binary data to a single compressed files?

Hey @mineirodf,

Welcome to the community :tada:

I suspect what you are after is a slightly tweaked version of the example on this thread: Downloading and Archiving Many Files Into A Single Archive - #2 by MutedJam the magic happens in the Merge Binary Data function node.

Give it a go and let me know how you get on.
