What does filo mean in either portoguese or spanish?

"Filo" is not a common word in either Portuguese or Spanish. It's more likely you're thinking of "filo" in Greek, which refers to a type of pastry dough used in dishes like baklava.

If you can give me more context, I might be able to help you find a translation. For example, what was the word used in, or what were you looking for?
