DataTransfer: files property

{{APIRef("HTML Drag and Drop API")}} 

The files read-only property of DataTransfer objects is a list of the files in the drag operation. If the operation includes no files, the list is empty.

This feature can be used to drag files from a user’s desktop to the browser.

[!NOTE] The files property of DataTransfer objects can only be accessed from within the drop event. For all other events, the files property will be empty — because its underlying data store will be in a protected mode.

Value

A {{domxref("FileList","list")}}  of the files in a drag operation, one list item for each file in the operation. If the drag operation had no files, the list is empty.
