## Method Details

### promptToOpenFile

public static JFileChooser promptToOpenFile()
Prompts the user to choose a file or a directory from their filesystems for our own devious uses. This method maintains the last directory the user visited before dismissing the dialog.

Returns:
  the JFileChooser that interacted with the user, after they are finished using it - null if no file was chosen
