Bug reports without an attached log file are usually useless.
Sometimes there a large files to be copied using WinSCP. So it takes time until the copy process is finished and I don't like to observe the copy dialog permanently. Therefore it would be interesting to know the total time of copying large files after a copy process (to assume the time duration for other copy processes with large files)
What would you use the information for?
