Robocopy (Robust File Copy for Windows) to Duplicate Files

Robocopy is a command line file copy software for you to copy files data since Windows Vista and Windows Server 2008. The syntax is:

robocopy source destination  [file[file]...]

For example, duplicate the file named test.docx, test.xslx, test.txt located in D:\My Files to E:\partition. The command is:

Robocopy E:\MyFiles\ F:\ff\ test.docx test.xslx test.txt /mt /z

• /mt: enable multi-threading for higher performance while transferring.

• /z: restart the transfer if it's interrupted.

All the files you specified will be transferred to the destination path. Or you could try the command to copy all files from the source path:

Robocopy E:\MyFiles\ F:\ff\ /mt /z (no files specified, it will copy *.* (all files) by default)

If you have already copied these files to the destination, Robocopy will skip all the files that be transferred to avoid the duplicate files.

Xcopy (Extended Copy) to Transfer Files

Xcopy is a command line tool for Windows operating system to copy multiple files or entire directory trees (files and subfolders) from one location to another.

It’s syntax is:

For example:

xcopy F: G: /s /e

• /s: Copy directories and subdirectories, unless they are empty.

• /e: Copies all subdirectories, even if they are empty.

And both of them has some limitations that:

• Robocopy and Xcopy does not copy open files.

• It’s quite difficult for those people who is not familiar with command line.

Or you may encounter the Xcopy does not copy all files error, and it’s troublesome. Find other fastest copy software instead.
