list manipulation – Export data to file

I have a function f(x,y,z,i) that returns the solutions {x1,y1,z1} for each step “i”.
I would like to use a repeating command (such as Do(…)) to get the outputs of this function f saved in a file. More specifically, I thought using something like Do(f(x,y,z,i),{i,1,10,1}) combined with Save, but I do not know how to combine these two commands with the interation of “i”
