The most simple way would be to utilize the PathAccessAuthorization event to detect opening of a file for writing:

var server = new FileServer();
...     
server.PathAccessAuthorization += (sender, args) =>
{
    if (args.Action == FileServerAction.OpenFile && args.RequestedOperations.HasFlag(FileSystemOperation.Write))
    {
        Console.WriteLine("Opening {0} for writing.", args.FullPath);
    }
};

An alternative would be to use a customized file system provider, but that seems to complex if all you need is to detect that a file has been opened for writing.

Thanks for answer!
No, it's not so simple, I don't need to use machine's file system. I need to use sftp server as middleware of file transporting. So I need to catch the stream and direct it to different remote server. How do you think what would be the best way to do that? Custom file system?
