One of my acquaintances wants to send me a file that is 10 GB in size but we're not on the same network, we're not even in the same city.

I told him I'll send him a URL of my computer where he can copy the file into. But it turns out my self-confidence was bigger than my networking skills as I'm still not able to solve this problem.

This is how I imagine this:

  • He writes \\myip\$C\ReceivingFolder or something like this in his Windows explorer and my shared folder would open.
  • It would use the public Internet, no same network
  • Anyone from around the world would be able to copy files in that folder if he owns this path
  • I don't care if it's risky

If this is impossible, I'm interested in any other solution that requires no third-party application/store only Windows built-in features and router settings (e.g. port-forwarding). At best we can use total commander if necessary.

Is transferring files between two computers via the public Internet possible in this way? How could I solve this? Please help!

  • You will have to use Remote Desktop (RDP) built into windows to transfer the file directly.

  • I don't want to share my whole computer with him, only 1 folder where he can copy to. Aug 15, 2019 at 22:38
  • Then you will have to use dropbox or similar service.

    Yes it is impossible unless the other pc is on the same local network, you have not provided near enough information to get a good or accurate answer.

    It is not impossible. It will require you to set up port forwarding on your router, identify your external address, and gather up a few other details. Doing so also exposes your network to certain risks. In your case, you might be better off handing him a flash drive.
