Knowing how to store, organise and retrieve information, regardless of what system is used (including computers, file cabinets and archive rooms) is a skill that doesn't just magically appear in your brain, you have to actually observe, trial or classically learn about it to make use of it. It used to be through day-to-day tasks and a growth in responsibilities when growing up that people got that skill semi-automatically, but that is no longer the case.
