I have been through these and they do not work. Part of it could be me, but if it is it because they are not given everything you need clearly. The best seems to be WiNSCP, but when I put it together, that is the Script file and run it from either a Bath file or the SSIS process task that they suggest it does not work.
 For example, they tel you that you need an SHH key, but do not tell you where to get it. I figured it ou, but there are a umber of other things that I am guessing and apparently wrong.
 need something that is more step by step and complete.
