Where do I copy my program onto the Console?

Hi, I am new to ComputerCraft and just made a simple program that locks my computer,
but now some of my friends want to use it too. So I copied it to a floppy, and went to their house. I used CP, but it said something "File not Found" I know I can't copy it to the rom because it's read only memory. And when I do Fs.copy it says program not found.
I have searched with Google and tried it with own computer not my friends but I don't get the results I am looking for…
I am really confused and could use any help, thank you!

Floppies are really unreliable, I usually just manually go into my files and copy them to specific/all computers.

If you are really new, allow me to recommend going to youtube and looking up rondouglas' videos. He's FunshineX on the forums here. He has a lot of videos and will teach you almost everything you need to know to get started. He also has a video on floppies, in case you are only interested in that. Just search "computercraft tutorial."

Thanks!!! Will go do that now

I did it, I used fs.copy in a program that I made, thanks Lettuce!

There's nothing unreliable amount floppes in my opinion. I've never had any issues storing files on them (Except for accidentally sticking them in infected computers :P/>/>)
