Oh, and here I always thought it just doesn't rename the file at all. NTFS is case-sensitive but Explorer is only case-preserving, so I thought it was just assuming I typed in the same name. When I wanted to change the case of a file name, I always renamed the file first to something else, eg. "Foo.txt" => "bar.txt" => "foo.txt". Thanks for the information :).

NTFS is case aware, but not really case sensitive.

How does that work? Did they implement case sensitivity and then decided to not use it?

It's more the case that NTFS is case-sensitive, but the Win32 APIs aren't.
