Re: too many parameters for command "open"
I got the same message when run command as below:
open -explicittls -passive=on ftps://username:passwprd@foo.com:50021 -rawsettings ProxyMethod=3 ProxyHost=proxy.net ProxyPort=8080 ProxyUsername=itdept ProxyPassword=testonly
What version of WnSCP are you using? Make sure you have the latest one.
