If you’ve mapped a network drive or server to your Windows PC via its IP address, you may see a warning message when attempting to transfer files from the network location to your local drives: These files might be harmful to your computer. Clicking “OK” dismisses the warning and transfers your files, so it’s not a major issue for occasional file transfers. But if you frequently transfer files between your local and networked PCs, having to dismiss this warning every time can quickly become annoying.
