When the following code is execute and the file already exists, the file is
not actually deleted (in file properties - created date does not change) -
but only the modified and accessed date changes.

No exception is raised.

How can I ensure that file is actually deleted? I want to raise create event
for another application which is monitoring this folder similar to file
system watcher.

Thanks.

if (!File.Exists(fileName))
{
File.Delete(fileName);
}

using (StreamWriter sw = new StreamWriter(fileName,false))
{
 sw.Write(content);
 sw.Flush();
}
