Put files from PC onto a Samsung Galaxy S7 via Wifi? I want to put files (images or pdfs) onto my phone as fast as possible using wifi (LAN over wifi). I don't care if it doesn't allow the files on the phone to be uploaded to the PC, I just want to put files onto the device from the PC.


PC is Windows 10 distro.
I don't want cables, over Wifi is wanted. 
I don't want to use the Wifi as an internet connection, I want all data to be sent along the local network (fastest).
I don't want to pay if possible.


Is there anything I can do to solve this?
SSHDroid + WinSCP. I think it doesn't even require root if not using port 22 (you don't have to). Also allows resume transfer. Been using the combination on my own tablet whose USB MTP connection is not working.

Don't expect transmission speed to be high, though - 2MB/s at best and ~200KB/s at worst, far slower than USB.
