Having worked on that code (in Packer) - the WinRM protocol is completely unsuitable for use as an SCP replacement. It's amazing it works at all even for small files! The actual "winrmcp" implementation is here https://github.com/packer-community/winrmcp if you're interested in the inner workings.

OK, but that code (cp.go) uploads base64 chunks of 8K and echo's them to a file and decodes when done. That surely isn't the real WinRM file copy implementation right?
Well... I just went looking for how it's implemented and holy shit I don't think they considered this case. Top results say "use a file share". Wow. I feel less inadequate.
Yep that's horrible whatever the basis for it is.
