After setting up Windows 10, you may still need to transfer all your files to the new device. Usually, you just use an external hard drive to copy your files and move it over the new device. Or if you’re a tech-savvy user, you probably transfer the files over the network to the new PC setting up file share.
While these are all good options, depending on the amount of data you need to transfer, using File Explorer, the process can take a very long time. If you want to copy (migrate) a lot of files faster and more reliably, you need a better solution, such as Robocopy.
Robocopy (Robust File Copy) is a command-line tool built into Windows 10, but it’s been around for years, and it’s a powerful and flexible tool to migrate files extremely fast.
In this guide, you’ll learn the steps to use Robocopy to quickly transfer a lot of files over the network on Windows 10.
The features included with Robocopy allows you to copy files very quickly, but remember that you’ll need a wired connection for the best experience. The time that will take to complete the transfer will depend on the network connection speed and disks performance.
This is a two-step process. You must first configure file sharing on the source device, and then use Robocopy in the destination device to perform the transfer.
In order to copy files between two computers, you must enable file sharing in the source device, so that Robocopy can access and copy the files from the destination device.
To share files on your local network using the express settings, use these steps:
Open File Explorer.
Navigate to the folder you want to share.
Right-click the item, and select Properties.
On the “Properties” window, click the Sharing tab.
Click the Share button.
Use the drop-down menu to select the user or group to share file or folder. For the purpose of this guide, select the Everyone group.
Click the Add button.
Under “Permission Level,” select the type of sharing permissions you want the folder to have. For example, you can select Read (default) if you only want users to be able to view and open files. If you select Read/Write, users can view, open, modify, and delete the content on the folder you’re sharing.
Click the Share button.
Note the network path for the folder that other users will need to access the content over the network and click the Done button.
Click the Close button.
After completing the steps, make note to of the folder path and the IP address of your source computer.
Once file sharing is configured on the source device, you can proceed copying the files using Robocopy from the destination device.
To use Robocopy to copy files fast on Windows 10, use these steps:
Search for Command Prompt, right-click the result, and select Run as administrator.
Type the following command to copy the files over the network and press Enter:
robocopy \\source-device-ip\path\to\share\folder C:\destination-device\path\to\store\files /S /E /Z /ZB /R:5 /W:5 /TBD /NP /V /MT:16
robocopy \\10.1.2.111\Users\admin\Documents C:\Users\admin\Documents /S /E /Z /ZB /R:5 /W:5 /TBD /NP /V /MT:16
In the above command make sure to change the source and destination paths with your configuration.
Robocopy has a lot of features that you can use, in the command shown in this guide, we’re using the following switches to make copy reliable and fast.
Perhaps the most important switch to pay attention is /MT, which is a feature that enables Robocopy to copy files in multi-threaded mode. Typically, when you copy files using File Explorer, you’re only copying one file at a time, but with multi-threaded enabled, you can copy multiple files at the same time better utilizing the bandwidth and significantly speeding up the process.
If you don’t set a number when using the /MT switch, then the default number will be 8, which means that Robocopy will try to copy eight files at the same time. However, Robocopy supports 1 to 128 threads.
In the command shown in this guide, we’re using 16, but you can set it to a higher number. The only caveat is that the greater the number, the more processing power and bandwidth will be utilized. If you have an older processor and a not reliable network connection, it could mean trouble, as such make sure to test before executing the command with a high number of threads.
You can always view all the available switches, simply run the
robocopy /? command. If you have any problems, you can submit your questions to the Pureinfotech forums.
