Don't assume they even know which folders have the data they want to protect. They don't. I once drove 60 miles to fix a printer problem for an office with 12 workers. The maid had unplugged it to plug in her vacuum cleaner.
Where I worked, when users had emergencies that any 12 year old could fix, we called it “polishing their screen.” It was a daily occurrence.
I work in a Helpdesk. I have callers who do not know where the start button or the taskbar are located despite me telling them where to look : )
