Hi David

If I understood you right, you need script like that:

@inherits UmbracoViewPage

@{
    var list = Umbraco.TypedMediaAtRoot();
}

@if (list.Any())
{
    <ul>
        <li>
            @foreach (var media in list)
            {
                <a href="@media.Url">@media.Name</a>
                if (media.Children != null && media.Children.Any())
                {
                    @RenderChildMedias(media.Children)
                }
            }
        </li>
    </ul>
}

@helper RenderChildMedias(IEnumerable<IPublishedContent> mediaItems)
{
    if (mediaItems.Any())
    {
        <ul>
            @foreach (var media in mediaItems)
            {
                <li>
                    <a href="@media.Url">@media.Name</a>
                    @{
                        if (media.Children != null && media.Children.Any())
                        {
                            @RenderChildMedias(media.Children)
                        }
                    }
                </li>
            }
        </ul>
    }
}

It renders all media items from all folders in the unordered list.

Thanks,

Alex
