OSDBuilder 19.4.11+ uses Content\DaRT by default. Previous versions of OSDBuilder use Content\WinPE\DaRT. You may continue to use the previous location without issues

Microsoft DaRT is not freely available. It is part of the Microsoft Desktop Optimization Pack (MDOP)


The purpose of the OSDBuilder\Content\DaRT directory is to contain the Microsoft Diagnostics and Recovery Toolset files. These files are used for customizing OSBuilds and PEBuilds

You can add Microsoft DaRT to the WinPE and WinRE images using OSBuilder in a few steps. If you don't know what DaRT is, have a quick read
