even if i switch single quotes with double quotes iam still getting erros.

I used the foreach statement finally.

You say while loops over na @array while it is true.(evaluated as a boolean)? what do you mean?

iterate!= loop ? I was picturing the statement while(@files) as loop over the array as long as it has items in it, and i though it was escaping after the last one.
