I want to run initialize a workflow on a folder (or a document set), and have all the documents in the folder be published in major version. I f the folder contains sub-folders, the documents in them should also be published.
How can I make such a workflow?
I think you just need to work out a Match case (filter) using the Check In Item action. With that action you can use a lookup to check in documents as a major version. So it can publish all documents in a library at once that match the filter.
