Automate Private key download of all file in a remote folder

I need some assistance.

I am trying to connect via windows task scheduler usuing winscp. I have a stored session which connects, authenticates using a private key, and I need to download all waiting files in a remote directory. This session works fine manually.

I need someone to assist me in writing a script to automate that series of actions. Is anyone willing to help?

Please read guide to scripting:
