Beyond Compare trialware by Scooter Software
What a great little piece of software, I’m amazed something like this didn’t come along sooner. Copying the complete contents of drives in Windows sucks. You’ll get about half way through a 40gb copy, and the windows copy feature will error out on a file. Of course Windows doesn’t copy the files in order, so you have no idea what’s missing. Beyond Compare solves that problem. Very, very handy.
