How to change Xref paths for multiple drawings in AutoCAD Products

Solution:

Use the Autodesk Reference Manager to modify reference paths for multiple drawings without having to open the individual drawings in AutoCAD.

The Reference Manager is included in the installation of any AutoCAD Product (except for AutoCAD LT) and can be found on the Windows Start menu, in the same installation folder as the product.
 

Note: the application is located at: C:\Program Files\Autodesk\AutoCAD 20xx\AdRefMan.exe
