I am using bittorrent sync for back-up from android phone to computer. So, First I designated the folder(A) to back-up on android. and back-up was well done. at this point, I have question. in order to recognize changes of files in folder(A) on android at Bittorrent sync application, it takes so much time, about 7-8minutes. So eventually back-up will start after 7-8minutes since back-up folder(A) has changed. plz let me know how to shorten the time to recognize??... if you do not understand my english, plz let me know as well.!! Thank you
