Hi everyone,

I'm working on a Client-Server project in which I let the server download updates which will be
spread over the clients.
To monitor changes to the downloaded updates (when some silly person manually deletes one of the
update files), I created a thread to monitor the directory in which the files need to be. For this I
use the FindFirstChangeNotification API.

It works pretty good. It detects the removal of the Directory and it detects the removal of any File
within the Directory.
BUT... when I delete the Directory when it contains files,  FindFirstChangeNotification doesn't
detect it.

I was pretty stumped when I found this out and have been searching through deja.com for any answers,
but couldn't find any.
Does someone has any idea what to do, or what i'm doing wrong?

Thanks in advance,


Peter Elbertse
