Ok, Thanks for your replies.
Too bad there is no easy way. I'm waiting for a lenghy file operation to
complete, therefore it would be nice to check to see when there are no
handles (at least from the app I'm waiting for). Unfortunately the file does
not seem to be locked, by the other process (I'm only reading it), but what
saves me is that it is in XML format, so it will not be well formed if I
grab it to early.

Hi Carl,
Only kernel mode code can enumerate which files are opened by other
processes, for example, the Handle utility
(http://www.microsoft.com/technet/sysinternals/ProcessesAndThreads/Han...
px) is using a driver to list all open handles by all processes.
Therefore your objective to do it in .NET might not be possible.
However, if a file is exclusively opened by other processes, an exception
will be thrown when you try to open it again in .NET.
Sincerely,
Walter Wang (waw...@xxxxxxxxxxxxxxxxxxxx, remove 'online.')
