How to save data in ascii format from a cell with a for loop?

Hi everyone!! I want to save data in ascii format from a cell with a for loop. For example if I have 2 files with different data in this case File{1,1} and File{1,2}, when I try to save data of each one for loop only saves me the first as you can see in the picture. I have no idea how to put a loop with a save function. I hope you can help me.

for k=1:numfiles
    Archivo{k} = File{1,k}
    save('Archivo','-ascii','-double')
end

Thanks in advance!!!
