# Automatically answer all prompts negatively not to stall
# the script on errors
option batch on
# Disable overwrite confirmations that conflict with the previous
option confirm off
# Connect using a password
# open user:firstname.lastname@example.org
# Change remote directory
# Force binary mode transfer
option transfer binary
# Download file to the local directory c:\ulti
get filename.txt c:\ulti\
# Exit WinSCP
What am I missing. I need to run a command line that gets the file in the remote folder every 15 minutes.
