You expect that. These users are savvy enough to shoot themselves in the foot, but not to understand they don’t know how to safely operate a gun. All they know is they’re on low disk space and there’s some large file somewhere they don’t recognise and want to get rid of.

Not to place all the blame on them, though. Many of these users were bitten by a misbehaving application in the past and had to figure out themselves how to fix their problem. Some of them took the opportunity to learn about their operating system, continued to explore and learn, and eventually became programmers. The others became obsessed with optimising their system and transformed into the prime target for malware-riddled “cleaner” apps which do more harm than good.
