Use WScript.Shell.Exec.

WinSCP example in JScript:

Generic WScript.Shell.Exec example in VBScript:
https://ss64.com/vb/exec.html

Just combine them together.

Has anyone been successful adding the text file line to a VBS script for automating the tasks? This is normally added and executed via batch file - Example: "C:\Program Files\winscp\WinSCP.com" "/script:C:\<location>\name.txt"

If so, please advise.
Thank you.
