My dad currently keeps all his data in a bunch of Word doc's. This includes all his personal as well as work correspondence and he also has a huge (1000+ pages) files in which he writes and maintains poems. He uses this as his scratchpad for new ideas as well as to copy and paste from his email.
I'm trying to find some software which will help him organize all this. Most importantly, I'd like him to stop using huge Word documents to store and find info because they are not at all well suited for the task, and if the file is damaged he'll lose everything.
But at the same time, the replacement can't be something which is too techie and is hard to use. It has to be free-form enough to let him use it without having to click around or understand a lot of jargon.
Right now I think my best bet is OneNote but I'm not too sure if its a good fit for large amounts of data.
