Windows 10 – Batch – Create a Folder Junction (also OneDrive)

email me

The NTFS file system provides the ability to create a system representation of a file or directory in a location in the directory structure that is different from the file or directory object that is being linked to. This process is called linking. There are two types of links supported in the NTFS file system: hard links and junctions.

A hard link is the file system representation of a file by which more than one path references a single file in the same volume.

junction (also called a soft link) differs from a hard link in that the storage objects it references are separate directories, and a junction can link directories located on different local volumes on the same computer. Otherwise, junctions operate identically to hard links. Junctions are implemented through reparse points.  more…

Basically, a junction just connects a source folder to a new target location…and Mklink is what makes the magic happen.

Example 1

Soft linking a Test folder and the Desktop folder

:: removing read only attribute
attrib "%userprofile%\Test" -r

:: deleting folder
rd /Q /s "%userprofile%\Test"

:: making link
mklink /j "%userprofile%\Test" "C:\users\%username%\Desktop"


Example 2

Soft linking C: drive profile\Desktop to D: drive profile\Desktop

attrib "%userprofile%\Desktop" -r
rd /Q /s "%userprofile%\Desktop"
mklink /j "%userprofile%\Desktop" D:\users\%Profile%\Desktop

Manually Testing

1. Move the contents of the user’s profile folder (example: Documents) to the OneDrive cloud storage sync location on their local hard drive: %userprofile%\Documents to

2. Create a GPO to redirect the Documents folder from %userprofile%\Documents to
%userprofile%\OneDrive\Documents. This can be done using either Folder Redirection policy, or a registry mod.

3. Ensure that the OneDrive sync client is installed on other enterprise computers.

4. When the user logs in for the first time on a new computer, they will authenticate to OneDrive.


Automated Redirect Solution

* Using the Desktop folder as an example…

Move Data
robocopy /MOVE /E /PURGE “%userprofile%\Desktop” “%userprofile%\OneDrive\Desktop”

Make Link
mklink /D %userprofile%\Desktop %userprofile%\OneDrive\Desktop

Update User Shell Folder
reg add “HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders” /v Desktop /t REG_EXPAND_SZ /d ^%USERPROFILE^%”\OneDrive\Desktop” /f

reboot, or reload explorer.exe
