    [Author:]

        Christian Penk

    Notice: this certainly needs a redesign - all those abstract-abstract classes which

    define stuff which is only needed in some parts makes this hard to understand.

    Especially the fact, that AbstractFileBrowser defines things both as abstract superclass

    and as a container is almost incomprehensable...

                                            question for files smaller.

                                            The initial default is 1Mb (1024*1024)
