Here’s a not-too-infrequent scenario:
What’s up with that file on my flash drive? I’d really like to delete it, but Windows keeps telling me “permission denied”. I’m pretty sure I have access to that directory.
Oh, I see. It’s in use by an application. Which one? Oh, it’s not going to tell me that.
Guess I’d better download a copy of Process Explorer.
Ah, there we are. That’s what’s holding that file. Ok. Terminating that program… Yay, now I can delete the file.
Now I’m just going to stop the drive so I can safely remove it…oh, look, the drive is still in use; it won’t let me stop it. Let’s see what Process Explorer says is in use on E:\…
Nothing. The drive isn’t in use after all. Yet I still can’t stop it.
*sigh* *yank*
…and now it’s bitching that I have to stop devices before removing them or risk data loss. Thanks, Windows!
