 When set to `true`, filtered files are restored with a `stream.PassThrough`, otherwise, when set to `false`, filtered files are restored as a `stram.Readable`.
 
 When the stream is a `stream.Readable`, it ends by itself, but when it's `stream.PassThrough`, you are responsible of ending the stream.
