How can I send a file via WiFi?

Projects General Guidance

I'm trying to use my Arduino WiFi Uno Rev2 to take a preexisting file on its SD card and send that file to another Arduino WiFi Uno Rev2 via WiFi. However, I want to do this without reading through the file and writing it to the client because I don't want my board to take too long to send this file, as it needs to be doing something else simultaneously. Instead, I want to try to send the file as a whole to the client and save that file to an SD card on the second Arduino board. Is this at all possible? Or do I have to read through the file and manually send the file line by line?

Not possible with the Uno. The Uno needs to read each byte in the file and send that byte out via some other channel.

Could this be possible with an Arduino Mega R3 with a WiFi board?

You ask for something like DMA capability. I can't imagine a Mega would make any difference.
