The dialog module provides functions to show system dialogs, so web applications can get the same user experience with native applications.

An example of showing a dialog to select multiple files and directories:

var win = ...;  // window in which to show the dialog

console.log(dialog.showOpenDialog({ properties: [ 'openFile', 'openDirectory', 'multiSelections' ]}));
