We could really do with a file explorer, I believe this is already available in your JQuery suite and is planned for .NET Core.
Syncfusion have already implemented an angular file explorer which can use Azure Blob Storage as a backend (though other backends are also available).
In fact the syncfusion file explorer is based on your own component. After some digging around looking for a similar solution I found their design document for the component which directly refers to the Telerik's own components. You may want to consider contacting syncfusion on this because it appears to me that they may have breached your copyright.
