Since Live CDs/Flash drives were invented, I wouldn't worry about this stuff any longer. Certainly have your personal files in a centralized location and backed up first.
Probably the easiest way to experiment these days is to create a VM and make snapshot, then start knocking down walls, just to see when and where the house collapses. Then revert and try something new.
There's a computer game that deletes random files when you make a mistake or lose.
There could be a competition!
