works very well needed to transfer about 54gb of data from one phone's ext sd card to another phone's ext sd card. connected the two phones via wifi direct, simply picked the right folder within zapya on the ext sd card from which I wanted to transfer, hit send (or whatever) and the transfer began and did not stop until finished, at an average transfer rate of around 2+ mb/second. saved me a huge amount of time in opening individual folders and picking individual files to send via phone's share via wifi direct option. Amazing!
