Subject line: Does work laptop expose shared folders?
Answer: If your machines are behind a router on your home network, chances are that no one outside of that network can see those folders.
Question in post: If I use my company laptop on my home network will the company then have access to shared folders on my home network?
Answer: The company would have no idea where the laptop is unless there is something running to "phone home" & tell it where the laptop is. Even if it did, the company couldn't see anything unless port forwarding was enabled.
