# Modes of Operation

The Kendo UI for Vue Upload enables you to manage the files for upload that will be rendered by setting the Upload into its [controlled](https://www.telerik.com/kendo-vue-ui-develop/components/upload/modes#controlled-mode) or [uncontrolled](https://www.telerik.com/kendo-vue-ui-develop/components/upload/modes#uncontrolled-mode) mode.

* The controlled mode gives you manual control over all the actions through the [`files`](https://www.telerik.com/kendo-vue-ui-develop/components/upload/api/uploadprops#files) property along with the [`onAdd`](https://www.telerik.com/kendo-vue-ui-develop/components/upload/api/uploadprops#onadd) and [`onRemove`](https://www.telerik.com/kendo-vue-ui-develop/components/upload/api/uploadprops#onremove) events.

* In uncontrolled mode the [`defaultFiles`](https://www.telerik.com/kendo-vue-ui-develop/components/upload/api/uploadprops#defaultfiles) are passed and the component handles the rest.
