When one is transferring files in Microsoft Windows, Windows will attempt to tell you how long it's going to take. A Windows hour can be 20 minutes, or it can be 5 hours. No one really knows!
I'm transferring 150 Gb of files to an external drive. It's currently sitting at 101 with an "hour" left. That's a Windows Hour, mind you.
