Available in workers

The webkitRelativePath read-only property of the File interface contains a string which specifies the file’s path relative to the directory selected by the user in an <input> element with its webkitdirectory attribute set.

Value

A string containing the path of the file relative to the ancestor directory the user selected.

  display: block;
  white-space: pre-wrap;
}

JavaScript

const output = document.getElementById("output");
const filePicker = document.getElementById("file-picker");

filePicker.addEventListener("change", (event) => {
  const files = event.target.files;
