There is not a simple way to do this, because the path shown in the RadFileExplorer's addressbar is used internally in the code of the control, so changing it may cause some unpredictable behavior. Indeed, the solution provided in this KB article
is the solution in your case. You can set physical paths to the RadFileExplorer's Configuration properties (as shown in the example attached to the KB) and then specify your mapping in the .mapping
All the best,
