The getFile() method of the FileSystemFileHandle interface returns a file object representing the state on disk of the entry represented by the handle.

If the file on disk changes or is removed after this method is called, the returned file object will likely be no longer readable.

Syntax

var File = FileSystemFileHandle.getFile();

Parameters

None.

Return value

A File object.

Exceptions

NotAllowedError

Thrown if the PermissionStatus.state is not granted in read mode.

Examples

The following asynchronous function presents a file picker and once a file is chosen, uses the getFile() method to retrieve the contents.

async function getTheFile() {
  // open file picker
  [fileHandle] = await window.showOpenFilePicker(pickerOpts);

  // get file contents
  const fileData = await fileHandle.getFile();
}
