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.

Example

In this example, a directory picker is presented which lets the user choose one or more directories. When the change event occurs, a list of all files contained within the selected directory hierarchies is generated and displayed.
