A word of warning about TerraCopy- it can cause annoying errors when copying. I transferred many gigs of data from one computer to another over a LAN, some files transferred fine, others looked like they copied ok, but were actually 0kb in size on closer look.

I'm not sure if it was a bug in that particular version or with the setup being used, but once I uninstalled TerraCopy the errors ceased.
