upload from nano to pc

Good evening.
i am busy with nano.
when a program is into the nano..en works fine.
then i am loosing the program from my computer.
how can i get it back from the nano?
or..if a collega want to copy it/clone it..how to do ?
thanks for thinking !!

You can't recover the program from the Nano. The code that you write gets turned into a series of numbers before it is uploaded to the Nano. You can download the numbers from the Nano but it would be almost impossible to re-construct the original program from the numbers.

Painful as it may be, it would be far far quicker just to re-write the program from scratch.


How you lose it? You sure it's gone?
