A method of automaticaly only copying changed files would be useful. So if I select a load of directories WinSCP could skip copying those files that have not changed (even if worked on byte count & / | date). For those files that had changed you could set a default option (resume/replace /skip/ ask). There was something like this in one of the ftp programs (which one I forget and don't have to hand).
Apart from this one minor niggle this is a great program, thanks.
