Drag and Drop (DnD) in local file system from browser

Hi there,

i have implemented a TreeGrid that lists the local file system of the client.

I want to add Drag and Drop functionality for files/folders from the TreeGrid (running in the vaadin ui / browser) to clients file system (to the desktop for example).
The action should the be a local move of the file in the client system.
That means the source of the drag-action should be the local path of the file, so that the client executes the move locally.

Is that possible, if yes, how?



Browsers have quite strict limits on what a web app can do with the file system, especially doing writes. What API are you using to list the files?
