Teracopy allows you to copy multiple files to another location very quickly and securely. I just recently used it to transfer 50GB from my old 100GB external to my new 500GB external drive. This did it very quickly and didn’t seem to lock up Windows at all and basically did it in the background without any interaction.
The interesting thing is that you just copy the files like you normally would in Windows and Teracopy takes over when the action happens. There is also a portal app version of this application out there so you can run it from your pen drive. If you are going to be copy mass amounts of files I would suggest using this application.
I have attached a copy of the most recent version but I would suggest going to their website to pull down the latest and greatest
