Windows 10 Persistent Map Drive to Folder (subst)

Jun 22, 2018

You can map a drive letter to a folder. Since my notebook only has 1 drive/partition, I wanted to created a D: drive which map to C:\d

subst D: C:\d

To make the drive mapping presist after reboot, we need to edit windows registry.

Click on Win10 Search, type regedit and click on run command.

Goto HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\DOS Devices, create new String Value and set Value name to D:. Edit the value and set value data to \??\C:\d.
