Connect to client's PC to access files using php or JS
===

Here is what I'm trying to achieve.

Write a php or JS program on my server that connects to a client's PC (outside of our network) and reads files or copies them to our server.

The client folder to read is going to be the same, ex: C:\MyCSV, although subfolder names will change.

My server runs Linux, it is sufficient to assume the client has a PC, not a MAC or Linux.

I'm not looking for code, I would like to know if this is possible using PHP or JS
