I'd like it to only copy new or changed files each time.

The issue I'm having is that robocopy copies all files each time (which takes around 12 hours). The drive contains around 800 GB of data with over a million files that are 20-80K each. You are not limited to copying files and folders to an external or internal drive, and this also works to migrate files over the network.I'm using robocopy to copy files to a samba share. Once you complete the steps, you will notice that copying files and folders will take significantly less time. As a result, make sure to test before executing the command with a high number of threads. If you have an older processor, using a high number will affect performance. The only caveat is that using a higher number will cause higher resource usage and bandwidth. In this command, we are using 32, but you can set it to a higher number. However, Robocopy supports 1 to 128 threads. If you do not set a number next to the /MT switch, the default number will be 8, which means that Robocopy will try to copy eight files simultaneously. The most important switch to focus on in the above command is /MT, which is the switch that enables Robocopy to copy files in multi-threaded mode.

/MT:32 - Do multi-threaded copies with n threads (default is 8).

/V - Produce verbose output, showing skipped files.

/NP - No Progress – don’t display percentage copied./TBD - Wait for share names To Be Defined (retry error 67)./W:5 - Wait 5 seconds before retrying (you can specify a different number, the default is 30 seconds)./R:5 - Retry 5 times (you can specify a different number, the default is 1 million)./E - Copy Subdirectories, including empty ones.

/S - Copy subdirectories, but not empty ones.

Robocopy has many features, and in the command shown in this guide, we’re using the following switches to make copy reliable and fast. For example, this command copies data from the drive “C” to “D” and uses the “32” threads for copying: robocopy C:\Users\admin\Documents D:\Users\admin\Documents /S /E /Z /ZB /R:5 /W:5 /TBD /NP /V /MT:32

In the command, make sure to update the source and destination paths and the options. Type the following command to copy the files and folders to another drive and press Enter: robocopy C:\source\folder\path\ D:\destination\folder\path\ /S /E /Z /ZB /R:5 /W:5 /TBD /NP /V /MT:32 Search for Command Prompt, right-click the result, and select the Run as administrator option. To use the Robocopy multi-threaded feature to copy files and folders to another drive faster, use these steps:

How to use multi-threaded feature with Robocopy In this guide, you will learn to use the multi-threaded copies feature on Robocopy to speed up the transfer process of files and folders to another drive on Windows 10. Instead of one file at a time using the copy feature built into File Explorer. One particular feature that makes Robocopy special (and often overlooked) is its multi-threaded feature that allows copying multiple files simultaneously.

Although this works perfectly fine, speed becomes a bottleneck as transferring many files can take a very long time.Īs an alternative, many savvy users use Robocopy (Robust File Copy), a command-line tool built into Windows 10 that offers more features to move data to a different location more quickly. On Windows 10, when you need to copy files to another drive, you typically use the standard select, copy, and paste process.
