HI and welcome to the Julia discourse! 
I fear the level of detail you are presenting is a bit too vague to provide proper help here. For example, just from a filename I feel it is near impossible to estimate what you plan to do. I also am a bit unsure what “Archivo 90” is and am a bit unsure which faculty you are referring to here.
Usually it is best to follow Please read: make it easier to help you with concrete questions.
