When it comes to copying files, Windows Explorer may probably be called reliable, but fast it is not. After the rewrite of the copy routines in Vista had caused much customer dissatisfaction, Microsoft rewrote the copy dialog again for Windows 7. But still, especially copying many small files takes ages.
And there are other problems: Explorer does not handle long paths at all. Files and directories stored in paths longer than 260 characters (MAX_PATH) are not copied by Explorer.
