David wants to know if there's a way to do file copy in Windows. Leo says that Microsoft offers a command line utility called RoboCopy that is far better than Windows own copy utility. It has verification built in.
XCopy is another option from DOS days. It's designed for multi file copying. Both are done from the command line. It will also "fail gracefully" and resume as well, rather than drag and dropping. Third party options include FastCopy, but avoid getting it from download.com since it adds junkware.
