How to make FileZilla over 10 Simultaneous Transfers on FTP protocol

short answer : you can open multiple FileZilla ... haha ......

long answer : you may be BAN from ISP , because FileZilla will send 10+ connection per time , it will be very like DoS attack , so you need test how many connections is allow , and wait like 60 sec to open next FileZilla process , and set the retry connections after 60 sec (like "Delay between failed login attempts") , finally enable the "Send FTP keep-alive commands" , you don't want reconnect when it has limits

have fun : )
