Setting path for a filemanager on load

I have json data (folderstructure) that I am setting to a filemanager component. I want to go to a specific folder path on load. How should I do it. I tried setPath method but the problem is my filemanager is not initialized. Is there a way I can set the path at the time of component initialization.

try using ready option

{
    ready: function(){
        this.setPath(folderId);
    }
}
