ESP8266 - Can or can NOT do

Hi,
I need help from someone who has worked with ESP8266. Looking about a month on the Internet to find a simple answer yes or no to the following question: Can ESP8266 to send a file * .txt saved on an SD card (file created by Arduino 2560) via FTP to a server. I managed through the wired network (using w5100), and works very well. I used the FTP code arduino.cc, of course with the necessary modifications.
Thank you very much.
