    ReadOnlyObjectProperty<File> selection = selectionModel.selectedItemProperty();
    selection.addListener((p, o, n) -> {
        folderName.setText(n == null ? "" : n.getParentFile().getAbsolutePath());
        fileNameLabel.setText(n == null ? "" : n.getName());
    });

    BooleanBinding isDirectory = Bindings
            .createBooleanBinding(() -> selection.get() != null && selection.get().isDirectory(), selection);
    edit.disableProperty().bind(isDirectory);

    files.addListener((ListChangeListener<File>) change -> {
        files.forEach(file -> {
            if (!fileReferences.containsKey(file) && file.exists() && !file.isDirectory()) {
                fileReferences.put(file, fileStore.getReference(file));
            }
        });
    });
    BooleanBinding disable = fileList.getSelectionModel().selectedItemProperty().isNull();
    open.disableProperty().bind(disable);
    edit.disableProperty().bind(disable);
    openFolder.disableProperty().bind(disable);
    removeFile.disableProperty().bind(disable);
