I think you can only do it thru code (and only find the process responsible) : http://stackoverflow.com/questions/860656/using-c-how-does-one-figure-out-what-process-locked-a-file

BTW - best practice is to use "using (stream.......)" which will take care of the dispose() for you (even if there's an exception in the block).
