Hello. I was just wondering why a ~6GB folder was transferring so slowly and was calculated taking 18 mins. After waiting a bit I realized the speed was not increasing, cancelled, quit C1, fired up AFT, copied the same folder to the same volume. Result: it only took 3 mins..

Not sure if you are aware and will provide a better MTP driver with C1 2.0 or if you need any more info or/ and data from me.
