It is similar to the copy command but more powerful as it can copy entire directories from one location to another. It is powerful enough to copy even drives. Xcopy is a fast command which can copy files and folders, overwrite existing files with or without prompt, exclude files based on name, path or extension, identify updated files, etc.
