If you’ve ever stared at a Windows "Copying..." progress bar that seems to be moving at a snail’s pace, you aren't alone. For years, IT professionals and power users have turned to a "secret" internal tool from Microsoft to solve this: .
Microsoft RichCopy is a multi-threaded file copy utility designed to optimize data migration and backups on Windows operating systems. The default Windows Explorer file transfer copies data sequentially—one file at a time.
