DataTransfer: files property
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
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 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.
