Copy large files over a Windows Remote Desktop Connection from a terminal.

I find it most convenient to use tsclient .

First, enable Drive Redirection.

1. Right click on the RDP file.
2. Go to the Local Resource Tab.
3. Click More... .
4. Choose Drive > OS (C:)

Next, Connect to the remote server and use the tsclient e.g., like this:

$ xcopy C:\tmp\my-large-file.csv \\tsclient\C\dev
