Want to use XCopy to copy only new or modified files 

Xcopy is a command line utility for copying multiple files or entire directory trees from one directory to another and for copying files across a network. Also, you are allowed to copy only new or changed files with it. And it is used in Windows 7/8/10/11/XP/Vista and Windows Server 2003/2008/2012/2016/2019/2022.

Copying only changed files with XCopy saves much time and disk space, thus many users are willing to only copy updated files. Below is an example from it.

“ I copy my files from Windows 7 to Server 2008 with the following command, but it copies everything.

xcopy C:\source X:\destination /s

I just want to use XCopy command to copy only newer files, because these files are very large. It’s time-consuming.

Is there a way to specifically just copy new or updated files without specifying a date? Any suggestion will be appreciated.”

How to copy only newer files in Windows 10 effectively

To copy only newer files in Windows 10, XCopy or Robocopy is a good choice for high-level users to perform batch operations. And It is able to backup only changed files instead of all files, even without booting into Windows

But the problem is you need to execute this operation manually every time, which may make you feel tired and time-consuming. And it's not user-friendly to most users for its high requirement. Thus, in this article, I'll introduce you to how to copy only changed files automatically without XCopy or Robocopy.

You need an all-in-one backup software - AOMEI Backupper Server to help you out. All the operations are based on an intuitive interface, so you can easily understand and use it like a professional. It provides you with 2 helpful ways to achieve this goal and you can choose to copy files with its original structure or compress it to an image file.

AOMEI Backupper Standard

Use XCopy to  copy only newer files 

Before using XCopy to copy only changed files, you need to learn the syntax and some parameters you will use.

Syntax of XCopy command line:  

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]

Options: 

  • /S  Copies directories and subdirectories, unless they are empty. If you omit /s, xcopy works within a single directory.
  • /Y Suppresses prompting to confirm that you want to overwrite an existing destination file.
  • /I   If in doubt always assume the destination is a folder. e.g. when the destination does not exist.
  • /E  Copy folders and subfolders, including Empty folders.
  • /D:mm-dd-yyyy  Copies source files changed on or after the specified date only. If you do not include a MM-DD-YYYY value, xcopy copies all Source files that are newer than existing Destination files. 
  • For more options, you can type xcopy /? for all the help or refer to xcopy command in Microsoft.
★Tips: To copy only updated files with XCopy, you have two options, namely using /s /d, or /i /d /y. And there are something you need to be aware:
This first option will copy files that does not exist in the destination folder if you use /d parameter without specifying a date. To avoid it, you could add the /u  switch.
The second option will ignore the new directories by default. To copy everything, including new directories, you should add the /e switch.

Now, see below and learn the detailed steps. Note that if there are spaces in your directory names, you need to use quotes.

Step 1. Type cmd in the search box and select it.

Step 2. Use XCopy to Copy only updated files with corresponding commands. Please remember to hit Enter after each one. 

#1: Copy only updated files that are not in the destination folder, type the following commands. 

set SourceDir=D:\Source

set TargetDir=K:\Target

xcopy %SourceDir% %TargetDir% /s /d

#2: Copy only changed files without new directories,  type the following commands. Please remember to replace “D:\Source” and ”F:\Target” with the path of your files.

set SourceDir=D:\Source

set TargetDir=K:\Target

xcopy %SourceDir% %TargetDir% /i /d /y

Xcopy Copy Only Newer Files
Xcopy Command Copy Only Newer Files

#3: Copy changed files already exists in the destination path, type the following commands: 

set SourceDir=D:\Source

set TargetDir=K:\Target

xcopy %SourceDir% %TargetDir% /s /d /u

#4: Copy everything including the new directory, type the following commands. Please remember to replace the following path “D\My Source\stuff” and ”F:\My Backup\stuff”.

Set SourceDir=”D:\Source\copy files”

Set TargetDir=”K:\Target\files copied”

xcopy %SourceDir% %TargetDir% /i /d /y /e

Step 3. Type exit and hit Enter to leave this window.

Use Robocopy to copy only new files 

Robocopy can also help you copy only new files, but it has more options than Xcopy and is considered as a good alternative. Before you use it, please learn the syntax and options you may use. 

Syntax of Robocopy command line: 

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

Options: 

  • /XO:  is used to exclude older files, and usually done with the parameter"/maxage: n".
  • /maxage: n:  indicates that the farthest modification time or the specific date, the file whose modification time or date is older than this will not be copied.
  • /XC: Exlude changed files.
  • /XN: Exlude newer files.
  • /XD dirs [dirs]:  Exlude directories mathcing given names and paths.
  • /S: Copy subdirectories, excluding empty ones
  • /Z: Restartable mode
  • /fft: Make the modify time comparison more tolerant(2 seconds granularity)
  • /Mir: Mirror a directory tree
  • For more options, you can type robocopy /? for all the help or refers to Robocopy command in Microsoft.
★Tips:
 To copy only changed files with Robocopy, you have two options, namely using maxage: n or /XO /maxage: n. 
Some users say that they don't want to create all the subfolders on the target disk if there is no new files in them. In this case, you need to add extra switch /S to exclude the empty folder.

Then, let's go through the following steps to copy only new files:

Step 1. Open the command prompt with administrator priority.

Step 2. Use Robocop to copy only newer or added files with corresponding commands. Please remember to hit Enter in order.

#1: Copy only newer or added files, type the following commands:

robocopy D:\folder1  E:\folder2  / maxage:7 or robocopy D:\folder1  E:\folder2  /XO /maxage:7

Robocopy Copy Only New Files
Robocopy Copy Only New Files

#2: Copy new files while excluding an empty folder, type the following commands.

robocopy D:\folder1  E:\folder2  /s /maxage:7 or robocopy D:\folder1  E:\folder2  /XO /s /maxage:7
