How to Remove Files from the FileList in HTML5 Drag-and-Drop Applications?

Removing Files from the FileList

In HTML5 drag-and-drop applications, accessing the dropped files is achieved through the FileList. However, the ability to remove specific files from this list is a common query and as such, we explore potential solutions.

Read-only FileList

According to the File API Working Draft, the HTMLInputElement's FileList attribute is read-only. This prohibits direct deletion of individual files from the list.

Clearing the Entire FileList

If the intention is to remove all files from the FileList, you can set the value property of the input object to an empty string:

<code class="html">document.getElementById('multifile').value = "";</code>

Alternative Approach

Instead of direct manipulation of the FileList, you can implement checks in your code that interacts with it. While this may seem cumbersome, it allows for more granular control and flexibility in your application logic.
