File Copy

I had a very interesting case recently where copied EXE files could not be deleted. They would simply remain in the folder like zombies, only to disappear a few minutes later.

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.
