Hi Daniel,

Regarding this issue of the creation of the file before or after the ytes
are written to the hard drive, I would like to tell you that when using the
Stream classes of the 'System.IO' namespace, data is not written to the file
immediately.  Instead, it is buffered to guarantee better performance for
file operations.  You can call the 'Flush' method to make changes to the
stream persistent.  Closing a file will also force writing data to the
physical disk.

Hence the file is created before the bytes are written to the hard drive.

Hope this helps.

Best Regards,
