Появилось надобность двигать файло в корзину.
До Vistы использовалось SHFileOperation в таком классе:

И потом по средствам RecycleBin.Send(путь к файлу) всё двигалось в корзину.
В Висте и Вин7 это уже не прокатывает. Т.е. никаких ошибок не выдаётся, просто не удаляется. Гуглс казал, что якобы надо использовать продвинутую версию IFileOperation. Но примеров использования я не нашёл, а сам ума дать не смог, как прикрутить.

НО раз идёт - пусть будет
