I'm gonna give you guys a quick tip today. There are lots of third party applications that can be used to copy files fast. But have you ever heard of RichCopy?
RichCopy is a tool that copies files super fast. Trust me, It is super fast! The best thing about it is, "It is made by Microsoft!!!". Yeah, you heard me right. Microsoft have made this tool for their internal usage. It was created by a Microsoft engineer named Dirk Benisch and was made in 1996. (Wonder why they didn't publish it though). But the good news is it's available for public download.
You can use it to copy a bunch of files or to copy a huge file super fast. Here's a screenshot of how it looks.
