Have you tried the File.exists() method?

  public boolean exists()

Tests whether the file or directory denoted by this abstract pathname exists.

Returns:true if and only if the file or directory denoted by this abstract pathname exists; false otherwise

(Basically, you would do something like if (new File("settings.dat").exists()) { ... }.)

Otherwise, you could go through Context.fileList() and look for the file there.
