-The hook accepts a `getFilesFromEvent` prop that enhances the handling of dropped file system objects and allows more flexible use of them e.g. passing a function that accepts drop event of a folder and resolves it to an array of files adds plug-in functionality of folders drag-and-drop.
-
-Though, note that the provided `getFilesFromEvent` fn must return a `Promise` with a list of `File` objects (or `DataTransferItem` of `{kind: 'file'}` when data cannot be accessed).
-Otherwise, the results will be discarded and none of the drag events callbacks will be invoked.
-
-In case you need to extend the `File` with some additional properties, you should use [Object.defineProperty()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/defineProperty) so that the result will still pass through our filter:
