I want to use a comparison tool (i.e. Winmerge, Beyond Compare) to sync two folder over internet.
The first folder is on the local PC, the second one is on a remote PC. Both the PC use Windows 10. They are not on the same network.
I can install any software on both of them. Which solution may work and how?
Installing a FTP Server?
Using a VPN? → how?
Using IIS? → how?
Installing an utility? → which one?
Is there a Window native solution for this task?
