Right-to-left Support
The RadFileExplorer fully supports right-to-left (RTL) language locales. In order to turn on the RTL support you should set dir=rtl to the html or body element or to its parent element.
<div style="direction: rtl;">
<telerik:RadFileExplorer RenderMode="Lightweight" runat="server" ID="FileExplorer1" Width="520px" Height="520px">
<Configuration ViewPaths="~/Images" UploadPaths="~/Images"
DeletePaths="~/Images" />
</telerik:RadFileExplorer>
</div>
