The essay is located in a susceptible area: the question of the file and its evils as we were bequeathed by the Freud’s works. Our intention will be to get to listen the Freudian impression aided by Derrida's reflections collected in his work Archive fever: a Freudian Impression. The phrase "the return of file" is a reference to that work and experience of registry promoted by Freud under the word Verdrängung. Heading into the thoughts of Freud and Derrida, try to outline the problems of file and its ills, its conditions of possibility and the unsettling questions of origin, the truth and the testimony.
