Try looking into FileSystemWatcher's Created event.

Some common occurrences, such as copying or moving a file or directory, do not correspond directly to an event, but these occurrences do cause events to be raised. When you copy a file or directory, the system raises a Created event in the directory to which the file was copied

I have came across something similar recently. I would use File's open write attribute on the file to see if you can write to the file: e.g. FileStream fs = f.OpenWrite();

if the above statement works then file is not in use i.e. done copying.

If you are using File.Copy() then this operation is finished after file is actually copied.

Periodically check for size. Anyway, I recommend you to use CopyFileEx, that has a progress feature (http://msdn.microsoft.com/en-us/library/aa363852(VS.85).aspx)
