How to send .txt file using nRF24L01+ with Arduino?

Hi!

I'm doing an Arduino .txt file sending project using the nRF24L01+. But i'm quite a noob in this so i'd like a bit of advice.

I'm using an Arduino Uno, and I made work simple examples but I can't find something consistent to teach me how to send files.

I'd like to type something in a .txt file and send to the other nRF24L01+ device and display the .txt file there.

By my guess, I will need to split off the file or send the content letter by letter or something like that.
