scheduled andAutomated file transfer between two computers on different networks

So i'm looking for a bit of network advice.

I'm trying to figure out a solution to a problem we are currently facing at work.

We're implementing a new system where we need to schedule an automatic transfer between an export folder on our office network to an import folder on a different network every day at a set time.

Basically i need to copy everything from the export folder to the import folder on the other network and afterwards move the content from the export folder to an archive folder on the same computer, at 10am every day.

What's the best practice here? I was looking in to creating an FTP server on the remote computer and automating it with winSCP. But is there a better way?
