Well, I don't know what to say... You are trying to clear up something to two people who speak in Spanish 24 hs a day
. Actually, Microsoft translates "file" to "archivo" and not "documento". That one is used for Word files (.doc).
In real life, a "documento" is a file of great importance, like a legal statement, a "carpeta" is a folder, and a "fichero" is a place where you keep files.
