By default, Robocopy will use 8 threads during the file compare, and copy steps. You can use /MT:16 to start your testing in finding the most optimal number of threads to give you the greatest efficiency and performance during larger projects.
Copy Long File Names Robocopy - The best free software for your
Microsoft engineers added the Low Free Space Mode /LFSM:n switch to assist IT Pros with larger file copy projects, especially pushing them to Azure File Sync cloud storage locations. The switch works best for tiered storage destinations which might run out of free space before the Robocopy command finishes.
Robocopy is a wonderful file copy utility every IT Pro should keep in their arsenal. It is continually being enhanced with new features, even on Windows 11, and we hope this guide gives you some ideas about how to integrate Robocopy into your workflow.
As @Leon Laude said robocopy supports long path, but some version (OS dependent), in the past, had problem with permission. You can also use -us/windows-server/storage/storage-migration-service/overview
ROBOCOPY will accept UNC pathnames including long pathnames over 256 characters long. Even though Robocopy successfully copies such files, choosing a destination folder with a shorter name than the source folder, can avoid issues such as difficulty accessing the files with Windows Explorer.
Backup a Server: The script below copies data from FileServ1 to FileServ2, the destination holds a full mirror along with file security info. When run regularly to synchronize the source and destination, robocopy will only copy those files that have changed (change in time stamp or size).

This software seems to be working very well. Couldn't find any bugs or anything worthy to report to their support. The program does what the description says it is supposed to do and it's very useful, especially for people who need to transfer files with very long names, and lots of them.
This software is like a Swiss Army knife, you can do so many things in terms of copying files and folders from anywhere to anywhere. It takes a bit of work to understand it, but it is expected. The admin guide and videos were able to provide us with all the details needed.
It has been very difficult to find a software that can copy files with long names. Someone recommended GS RichCopy 360 as a tool, and it worked as advertised. Their pre-sales support responds promptly. We have a companywide license, and it is the only tool we use to migrate servers and workstations.
We needed a solution to copy millions of files and folders from one server to another. GS RichCopy 360 was the only one that was able to copy files in long paths and open files with no issues.Support from GuruSquad was reachable by phone and quickly answered our questions and gave us recommendations.
Unlike Xcopy, Robocopy is used to mirror or synchronize directories. Robocopy will be able to check the target directory and delete files that are no longer in the main tree, instead of copying all files from one directory to another. It will also check the files in the target directory against the files to be copied, and will not waste time copying unchanged files.
The basic syntax of the robocopy command is: robocopy [source] [destination]. There are various options you can use with the robocopy command to meet different needs. Click Windows Robocopy Command to see more. Next, I will explain how to use the Robocopy command to trsansfer files from one location to another.
While these are good options, depending on the amount of data you have to transfer, the process can take a long time from File Explorer. If you want to copy a lot of files faster and more reliably, you need a better solution, such as Robocopy.
I can sync a folder pair consisting of my main photo library and a folder on my network drive. And like with SyncToy, Robocopy will also delete files on the network drive that no longer exists in my collection. Best of all, Robocopy is free (it comes built-in to Windows).
Why such a long blog post on a single utility? Just feast your eyes on the tables below. You have a lot of options to copy or move files with robocopy! You will more options in the individual sections.
When copying files over a network, you can use the /IPG switch. This is also known as the inter-packet gap option. This option defines (in milliseconds) the frequency in which robocopy will wait between sending new packets.
A typical job file created with robocopy has an RCJ extension and looks like the below snippet. This job file was created by running robocopy C:\src D:\dst /save:myjob. You can see that you can provide comments in the job file using :: which is most of what this file has.
Saving a job file is as simply as appending the /SAVE: option to the end of your syntax. Replace with the name of the job. The /SAVE option will create a file called .rcj in the directory where you ran robocopy.
You must specify /SAVE as the last option. Any options specified after /SAVE will not be added to the job file. Also, note that even if an existing job file already exists, robocopy will always overwrite the existing one. Backup or version control your job files!
By default, using /RH will check for the start time before the entire run. However, if you have a lots of files and believe the process may go longer than that, you can use the /PF option. /PF will force robocopy to check the window before every file.
I have used many or I can say almost all of the file copying software available in the market. But none of them yielded satisfactory results for me. They failed at one point or other. If someone provided long path name support then it does not provided multi threaded file transfer or pre scheduled file transfer. I was searching for a software which was simple to use and yet being very powerful. One of my friend suggested me to use GS Richcopy 360 and till now I am using it. Its been 2 years now. Some of its features include long path name support which is necessary when copying huge files, copying locked files, multi threaded file transfer for fast transfer speed, pre scheduled file transfer, email notification when task is done and many more.
I've been happily using robocopy for backing up my computers to an external usb drive. It's great since it only copies the files that were changed/updated/new. I can take my external drive to any machine and look at it just as if it's another drive on the computer.
I've recently purchased a 750g and another 1tb external hard drives. I ran a robocopy over the weekend that copied about 500g to my external drive. After the copy My Computer shows that 500g has been used on the external drive. The strange thing is that when I click on the drive in Windows Explorer, nothing shows up in the right pane of Windows Explorer (and the + goes away in the left pane). I copied a single file (drag-and-drop) to this drive and it shows up in Windows Explorer. Command Prompt show the same thing. 1 file.
You can prevent the new directory from becoming hidden by adding the /A-:SH option/flag/switch to your robocopy command.See this Server Fault Answer to "Why does RoboCopy create a hidden system folder?" for more information.However, this may or may not prevent copying system attributes in other folders, according to this discussion on the Microsoft forum "ROBOCOPY hides destination Directory".
Here is an example taken from my longer, more thorough, Answer on Super User to the Question "How to preserve file attributes when one copies files in Windows?":Robocopy D:\ C:\D_backup /A-:SH /DCOPY:T /COPYALL /E /R:0 /ZB /ETA /TEE /V /FP /XD D:\$RECYCLE.BIN /XD "D:\System Volume Information" /LOG:C:\D_backup_robocopy.LOG /MIR
However, using the /A-:SHA parameter did work and my top level destination directory was not given the system or hidden attributes. Weirdly, my drive does not have the "a" (archived) attribute set so I am dumbfounded as to why this works at all. I do prefer simply removing these attributes to only the root destination folder after completion of the robocopy command per Ricky's suggestion so that these attributes are respected for any sub-directories. Though the /A- switch is easier to manage and (for my backup purposes) are not relevant to any directories I am backing up. You may want to consider not removing the system or hidden attributes if you're backing up your C:\ drive though.
Combine the Path, Filter, Include or Exclude parameters to refine the copy process even further. If you use Include and Exclude in the same call, PowerShell ignores Exclude. You can also supply an array of filenames. The path is simplified if your working folder is the source folder for the copy.

Robocopy is the tool to use when working with entire directories, since that's what it was designed to do. Let's say you want to "mirror" directories, i.e., make two directory trees contain identical files/folders. This is similar to using the /E switch (which is covered under the tip titled "Using Robocopy to Copy Entire Directories") along with the /PURGE switch. (The /PURGE switch tells Robocopy to delete destination files/folders that no longer exist in source.) The shorthand switch to mirror directories is /MIR, so the command to mirror directories is:
RoboCopy is the most popular and traditional way to copy and replicate files over a network on Microsoft Windows platforms. It uses the concept of timestamp and datestamp for the transfer of files which helps out in the tolerance of network interruptions. It is avoided by many people because of the complexity of the command line. To overcome the CLI problem, you can use these 6 best RoboCopy GUI for Windows 11 and Windows 10. 2ff7e9595c
