 // File contains the fileBrowserHandlerInternal.selectFile extension function.
 // The function prompts user to select a file path to be used by the caller. It
 // will fail if it isn't invoked by a user gesture (e.g. a mouse click or a
 // keyboard key press).
 // Note that the target file is never actually created by this function, even
 // if the selected path doesn't exist.
