    Good morning Nghia,

    Thanks for your question. I wouldn't think of those as “folders” as they are actually “Programs,” with their own Main Routine, Sub-routines, and Local (Program) Tags.

    “Programs” are scheduled to run in a particular within a Task, and the best use cases having more than one “Program” in a task is when the programs are either duplicates of each other (Line 1 vs Line 2,) or they control completely different parts of a system.

    Hope this helps!
