File Duplication

File duplication, also named file copy, means you could copy files from one location to another, and the new created file has the same content as the existing file, including the file format, file size and the content of the file. The file duplicates are the same as the original one as long as the source file not changed yet.

Copying files is common in our daily life, and there are two traditional ways: Copy & Paste, Drag & Drop. And you could copy files via the two ways in all Windows operating system (OS).

Why Duplicate Files in Windows 7/8/10?

As we all known, duplicating file gives us a lot of convenience to make our life easier, such as:

  • Save our time.

  • Share files with our friends or family.

  • Reduce complex editing work.

  • Backup your important documents in case of data loss.

  • Transfer files from one computer to another one especially from a old computer to a new one.

As a matter of fact, the Microsoft Windows has built-in some file copy software depending on your Windows version.

Robocopy (Robust File Copy for Windows)

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>[ ...]] [<Options>]

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.

Robocopy Copy Files

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)

Robocopy Copy All Files

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)

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:

Xcopy <Source> [<Destination>] [/w] [/p] [/c] [/v] [/q] [/f] [/l] [/g] [/d [:MM-DD-YYYY]] [/u] [/i] [/s [/e]] [/t] [/k] [/r] [/h] [{/a | /m}] [/n] [/o] [/x] [/exclude:FileName1[+[FileName2]][+[FileName3]] [{/y | /-y}] [/z] [/b] [/j]

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.

Xcopy Duplicate Files And Folders

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.
