BookmarksToFile от Sergio Ll.

BookmarksToFile converts your bookmarks into URL shortcut files (.URL, .desktop or .webloc for Windows, Linux and Mac respectively).
When clicked, all your bookmarks will be shown in a treeview. This view will allow you to select which bookmarks you want to convert and the files are delivered in a zip file. Alternative, you can download all your bookmarks by clicking a button.
