It might by a local antivirus scanning the partially transferred file.

In scripting you should not rely on saved sites, use this command instead:
open ftp://User:Pass@MYFTPSERVER/
Connecting to MYFTPSERVER ...
Connected
Starting the session...
Session started.
Active session: [1] FTPSERVER
transfer binary

Thank you for the correct syntax!

Sorry are you referring to bandwidth, server ram/cpu resources, or something I am not aware of? The servers are at a colo with burstable bandwidth to 1gb. My office (where they are transferred to) has 75mb down.

I have a small time frame that I need to transfer these files (8GB in totals for all 5 zips) is the reason I am trying to send them all at once versus 1 at a time.

You would have to run 5 separate scripts in parallel.

You can use a batch file like this:

start "" winscp.com /command "open FTPSERVER" "D:\1.ZIP" "exit"
start "" winscp.com /command "open FTPSERVER" "D:\2.ZIP" "exit"
start "" winscp.com /command "open FTPSERVER" "D:\3.ZIP" "exit"
start "" winscp.com /command "open FTPSERVER" "D:\4.ZIP" "exit"
start "" winscp.com /command "open FTPSERVER" "D:\5.ZIP" "exit"

Though note that 5 parallel uploads are too much, that will hardly give you a better performance than 2-3.

Forgive me for novice question.

I am using the following basic batch/script to copy 5 files to my FTP server.

option batch on
option confirm off
open FTPSERVER
option transfer binary
put D:\1.ZIP
put D:\2.ZIP
put D:\3.ZIP
put D:\4.ZIP
put D:\5.ZIP
exit

I am fairly sure WINSCP sends the 5 files 1 at a time in the order above. I looked around and I saw a few different posts about how to get WinSCP to transfer all 5 files at the same time but it is not working. Could someone give me the proper syntax to send all at same time?
