Speed Up File Transfers in Windows 11 with Robocopy

Robocopy is a built-in Windows 11 tool that moves large folders and big files much faster than dragging them in File Explorer 📁. Short for Robust File Copy, it handles massive data transfers without freezing or slowing down your PC.

You can speed up network file transfers even more by combining Robocopy with SMB compression, which shrinks data while you send it between computers.

Copy files over the network using Robocopy

As mentioned, Robocopy is a command-line tool that lets you copy files faster when SMB compression is enabled. In Windows 11, SMB compression mode is active by default.

Preparation starts with enabling file sharing on both machines.

First, make sure to enable file sharing on both computers. Share the folder containing the files you want to transfer next.

Knowing the name or IP address of the other computer remains necessary.

That information lives within the following article.

• How to enable file and printer sharing in Windows 11
• How to share files and folders in Windows 11
• How to find your computer name in Windows 11

With required details in hand, copying files using Robocopy comes next.

Before launching Robocopy, adding account details to Windows 11's credential manager prevents authentication headaches. Windows remembers login information for the other computer this way.

cmdkey /add:COMPUTER or IP /user:COMPUTERNAMEUSERNAME /pass:PASSWORD

Replace COMPUTERNAME with the name of the target computer and USERNAME and PASSWORD with credentials belonging to that machine.

Domains allow substituting COMPUTERNAME with the domain name.

Computer names also substitute cleanly for IP addresses.

Here’s an example:

cmdkey /add:192.168.1.2 /user:WORKGROUPgeekrewind /pass:password

After running those commands, use the format below to copy files with Robocopy and SMB compression.

robocopy \source-ip-addresspathtoremotesharedfolder C:local-devicepathtodestinationfolder /E /Z /ZB /R:5 /W:5 /TBD /NP /V /MT:16 /compress

Here's an example:

robocopy \192.168.1.2DocumentsRemoteSharedFolder C:UsersgeekrewindDocuments /E /Z /ZB /R:5 /W:5 /TBD /NP /V /MT:16 /compress

Pressing Enter triggers file transfers to the target device.

Here's a breakdown of the Robocopy options:

• /E — Copy Subdirectories, including empty ones.
• /Z — Copy files in restartable mode.
• /ZB — Uses restartable mode. If access is denied, use backup mode.
• /R:5 — Retry 5 times (you can specify a different number, the default is 1 million).
• /W:5 — Wait 5 seconds before retrying (default is 30 seconds).
• /TBD — Wait for share names To Be Defined (retry error 67).
• /NP — No Progredon'tdon’t display percentage copied.
• /V — Produce verbose output, showing skipped files.
• /MT:16 — Do multithreaded copies with n threads (default is 8).
• /compress — Enables SMB compression to speed up transfers over the network.

That wraps up the process.
