Have looked over a few of the comments here and they seem like mostly good advice. The only things that I can think too add are that it is worth taking the time to explain to your parents the benefits of filing things in one location and showing them an easy way of backing it up regularly (and explain why otherwise it won't happen).
Having just had to comb through the remnants of my deceased Fathers hard drives looking for that vital information that he forgot to file in a safe place I can tell you that one day this will save you a lot of grief and heartache.
On the flip side make sure that they DO have access and all the passwords written down somewhere so that should you get knocked over by a bus tomorrow then they don't suddenly have a completely useless machine which they can't do anything with without reformatting the drives.
