File and printer sharing is a feature that enables other computers on a network to access resources on your computer. When using your mobile PC in a hotspot, it’s best to disable file and printer sharing because when enabled, it leaves your computer vulnerable to hackers. Remember, though, to turn this feature back on when you return to the office.
