Why can't I use Windows CIFS (Folder Sharing) on ​​the internet without a VPN?

Question

VPN

I saw mentions that you shouldn’t do this, and you need webdav / samba / vpn, but why can’t you share a network folder with a user with a password, forward ports and open it from the Internet?

Answer 1

Well, why not? Can. Do it. Only when they break - do not say that you did not warn.
