How to automatically save a file in two local folders?

Question

JavaScript

I have a folder with a project on my computer, and a remote network drive (like from a hosting) is connected. But it does not have the ability to connect via ftp. I need that when saving a file in a local directory, the same file is saved (added, replaced) on a remote network drive. It is visible on my computer as drive X:/
If there was access via ftp, then there would be no problems. There is package SFTP for updating files on a remote server. How to solve this issue?
