WiFi File Transfer

Good navigation controls in concept. But there's a bug, I think. A folder on external storage wouldn't reorder by date - either ascending OR descending, so i had to search a long way down to find the files i wanted. Individual files can be transferred en masse from PC to external SD on phone. There is a 3mb size limit. But what they don't mention is they file transfer from phone to PC has to be done one. by. one...aaargh. This even though the menu offers individual transfer of multiple selections. Maybe that's another bug. I appreciate the nice interface with facility to view photos large. That's great. Appreciate, too, access to external phone storage. But the other problems are annoying enough that I'm going to keep looking for an app without them.
