And if you are using Windows you can install Cygwin to avoid having to 
deal with Microsoft-specific PowerShell and use industry standard shell 
commands instead - it's free and open under GPL:

For transferring large numbers of files I prefer rsync because it uses 
an uncommonly smart algo to avoid re-sending things that have already 
been sent, and has an on-the-fly compression option for quick transport:
<http://en.wikipedia.org/wiki/Rsync#Algorithm>

I most commonly use the "-avz" options when transferring outside my 
local network (just "-av" for local, since the compression isn't as 
useful over Gb ethernet):

  rsync -avz ~/LocalFolder/  user at server:/RemoteFolder/

...where:

a = archive mode, which is recursive and maintains mod dates, etc.

v = verbose, so you see a list of what's sent; if you don't need that
     you can safely omit the "v"

z = on-the-fly gzip compression of file chunks for faster transport

Digital Ocean has a good introductory tutorial on rsync:
